Notizie e Link Interessanti / Come disabilitare sync in OSX ...
Ultimo messaggio di Max Brezzi - Mercoledì, 26 Ottobre 2016, 16:04:56 PMDomanda
ragazzi non so come fare a disabilitare l'upload di scrivania e documenti su iCloud drive. Mi spiego: ho selezionato durante l'installazione l'upload su iCloud Drive di scrivania e documenti ma poi mi sono reso conto che in realtà è una manovra della apple per costringerti ad acquistare più spazio. ora non riesco a deselezionare la scelta perché se vado in opzioni di iCloud drive e deseleziono scrivania e documenti mi avvisa che li toglie dal mac lasciandoli solo su iCloud drive, cioè il contrario di quello che volevo. HELP!
Risposta
Per star sicuro puoi procedere così: Facciamo finta che ti chiami "Mario" (giusto per dare un nome alla cartella home quella che contiene Documenti, Download, Immagini, ecc...).
Vai nella cartella Mario e crea due nuove cartelle ad esempio DocumentiBackup e ScrivaniaBackup.
Sposta l'intero contenuto della "vera" cartella Documenti in DocumentiBackup, poi fai lo stesso spostando il contenuto di Scrivania in ScrivaniaBackup.
A questo punto Documenti e Scrivania saranno vuoti!
Disattiva da Preferenze- iCloud - icloud drive opzioni "Cartelle Documenti e Scivania"
A questo punto può cancellare quello che vuole... Tanto sono vuote!
Dopo riavvia il mac e rimetti i tuoi file nelle rispettive cartelle come prima!
Ci sarà la seccatura di dover riposizionare file e cartelle sulla scrivania come più gradisci.
Sicuramente ci sarà un metodo più rapido ma quello che ti suggerisco è sicuro al 100%....
In ogni caso prima fai un bel backup!

Creazione di un programma di installazione avviabile per OS X
Con OS X El Capitan, Yosemite o Mavericks puoi usare un'unità flash USB o un altro supporto rimovibile come disco di avvio da cui installare OS X.
Questi passaggi avanzati sono destinati principalmente agli amministratori di sistema e ad altre persone che hanno familiarità con la linea di comando.
Uso del comando "createinstallmedia" in Terminale
Scarica il programma di installazione di OS X dal Mac App Store. Chiudi il programma di installazione se si apre automaticamente dopo il download. Il programma di installazione si troverà nella cartella Applicazioni.
Attiva l'unità flash USB o un altro volume. Inoltre potresti usare una partizione interna secondaria.
Apri l'app Terminale, disponibile nella cartella Utility della cartella Applicazioni.
Usa il comando createinstallmedia in Terminale per creare il programma di installazione avviabile. Nella sezione successiva sono disponibili esempi di questo comando. Per istruzioni dettagliate per l'utilizzo assicurati che l'app Installa OS X appropriata si trovi nella cartella Applicazioni, quindi immetti uno dei seguenti percorsi in Terminale:
Percorso per El Capitan:
/Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia
Percorso per Yosemite:
/Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia
Percorso per Mavericks:
/Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia
Esempi
Questa è la sintassi di base del comando. Sostituisci volumepath con il percorso dell'unità flash USB o l'altro volume e sostituisci installerpath con il percorso dell'app Installa OS X.
createinstallmedia --volume volumepath --applicationpath installerpath
Nei seguenti esempi si presume che il programma di installazione di OS X si trovi nella cartella Applicazioni e che il nome dell'unità flash USB o dell'altro volume sia MyVolume:
Esempio per El Capitan:
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app
Esempio per Yosemite:
sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Yosemite.app
Esempio per Mavericks:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Mavericks.app

L'app Disk Utility ha sempre contenuto la funzione che permetteva di verificare e riparare i permessi del disco su Mac, ma nell'ultima versione di OS X questa funzione è stata rimossa. Questo però non significa che non potete più verificare e riparare questi permessi su OS X El Capitan. Sarà necessario scrivere qualche linea di comando per avviare manualmente la verifica.Per essere più chiari, la riparazione dei permessi è considerata una sorta di hocuspocus con piccoli benefici in molte situazioni, ma chiaramente non è l'unica causa dei problemi che potrebbero verificarsi in OS X.
Come riparare Verifica i permessi del disco su OS X El Capitan:
Aprite il Terminale, click sulla lente di ingrandimento in alto a destra e digitate "Terminale", inserite il seguente codice per verificare volume di default:
sudo /usr/libexec/repair_packages –verify –standard-pkgs /
Se volete invece verificare i permessi su un drive differente, specificate il volume con uno "/"
Niente paura, vi verranno mostrati una serie di permessi, diversi fra loro, un po' come l'immagine qui sotto:
The command will run and either show permissions that differ, or nothing, depending on what's found. Not surprisingly, you'll likely find some variation of permissions that differs, looking something like:
Permissions differ on "usr/libexec/cups/cgi-bin", should be drwxr-xr-x , they are dr-xr-xr-x .
Permissions differ on "usr/libexec/cups/daemon", should be drwxr-xr-x , they are dr-xr-xr-x .
Permissions differ on "usr/libexec/cups/driver", should be drwxr-xr-x , they are dr-xr-xr-x .
Permissions differ on "usr/libexec/cups/monitor", should be drwxr-xr-x , they are dr-xr-xr-x .
Come riparare i permessi del disco su OS X El Capitan via linea di comando:
Se volete riparare i premessi, rimpiazzate il flag "verify" con "repair" e puntate nuovamente lo stesso volume:
sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /
La riparazione dei permessi spesso richiede un po' di tempo, proprio come accade con Disk Utility.

Se eseguirete il comando repair_packages senza sudo e senza specifici flag, riceverete una guida "help" come questa qui sotto:

Usage: repair_packages [ARGUMENTS]...
Commands:
--help Print this usage guide.

--standard-pkgs Verify or repair the standard set of packages.
--volume PATH Perform all operations on the specified volume.
--output-format # Print progress info using a special output format.
--debug Print debuging information while running.
Come vi abbiamo detto prima, questa operazione non fa parte dalla manutenzione di routine per un Mac ed è raramente necessaria, potrebbe essere anche una ragione per spiegare il motivo dell'espulsione di tale funzione da Disk Utility.
In ogni caso, qualsiasi release di OS X permette di recepire comandi dati da terminale.

Ultimo messaggio di Max Brezzi - Martedì, 23 Giugno 2015, 11:52:06 AMhttps://openvpn.net/index.php/access-server/docs/admin-guides/183-how-to-connect-to-access-server-from-a-mac.html
Documentation
To connect to Access Server from a MacOSX client computer, you need to follow these steps:
Download and install an OpenVPN client for MacOSX
Login to the Access Server's Client Web Server and download the appropriate client configuration file (typically called "client.ovpn")
Run the OpenVPN client with the downloaded client config file
A popular OpenVPN client for MacOSX is Tunnelblick. It can be obtained for free from https://tunnelblick.net. Follow these basic steps to use Tunnelblick with OpenVPN:
Download the Tunnelblick disk image file (a ".dmg" file) from https://tunnelblick.net
Open the downloaded disk image file (which mounts the disk image).
Double-click the Tunnelblick icon (it may be labelled "Tunnelblick.app") and you will be guided through the installation of the program.
Once you have installed Tunnelblick, you can install the configuration file. Decompress certificate ZIP and find xxxx.ovpn file and double-click it. This will launch Tunnelblick if necessary, and Tunnelblick will install and secure the configuration.
Run Tunnelblick by double-clicking its icon in the Applications folder. If left running when you logout or shut down your computer, Tunnelblick will be launched automatically when you next log in or start your computer.
The first time Tunnelblick is run on a given Mac, it will ask the user for the an system administrator's username and password. This is necessary because Tunnelblick must have root privileges to run, as it modifies network settings as part of connecting to the VPN.
For more information on using Tunnelblick, see the Using Tunnelblick at https://tunnelblick.net/czUsing.html.

Ultimo messaggio di Max Brezzi - Mercoledì, 17 Dicembre 2014, 18:10:12 PMUseful YouTube URL Tricks
BRIAN YANG / AUGUST 21, 2010 / 141 COMMENTS
YouTubeEver wanted to share a YouTube video with someone but want to share just a certain part of it without having them start from the beginning? Need to have a video automatically loop?
YouTube URLs can be modified with various query string parameters to change certain features and how to video player works. In most cases, parameters follow the video URL with an ampersand (&). The most commonly seen parameter is probably &feature=related which shows that the video was found through clicking on a Related Video. This parameter basically does absolutely nothing for the actual user though.
This guide is outdated. Check out my updated version of this guide, including an easy to use URL and embed code generator, at the following link:
Useful YouTube Player Parameters
There are many URL parameters you can add to YouTube video URLs as well as the embed codes. Let's start with the video URL.
Click here to jump to the Embedded Video URL Parameters.
Video URL Parameters
There are parameters to add to the URL of a YouTube video. Video ID is a placeholder for the YouTube video ID which is the string of alphanumeric characters after the watch?v=.
High Quality Videos
YouTube supports up to HD quality videos, but some videos might not have an HD format available. Some might just have a High Quality option available. To create a link that automatically loads the video in HQ or HD, simply add &fmt=6 (480p HQ FLV), &fmt=18 (480p MP4) or &fmt=22 (720p HD) to the end of the video URL.
Update: YouTube has made many changes recently and the fmt parameter does not seem to work anymore. For HD, add &hd=1 instead. The fmt parameter no longer does anything.
This example video link will start automatically in 720p HD (&hd=1).
http://www.youtube.com/watch?v=Video ID&hd=1
Skip to Specific Time
Suppose you're trying to share a video clip with someone, but you don't really think its necessary for them to watch the whole thing from the beginning. You can specify where the video should start as well as easily jump to a specific point by adding #t=7m30s. The number in front of the 'm' is the minute and in front of the 's' would be seconds. In this example, I'm skipping to 7:30.
This example video link will automatically skip to 1:32 (#t=1m32s).
http://www.youtube.com/watch?v=Video ID#t=1m32s
Browser Window Full Size Player
This will load a large player that fills your entire browser window.
Simply replace the '?' and '?=' in the URL to '/' and remove 'watch'.
http://www.youtube.com/embed/Video ID
This example video will start in a full size player.
Prevent Video from Autoplaying
Same procedure as using the large player. This player does not start playing automatically. If you are using this full size player and want it to autoplay, then simply add ?autoplay=1 to the end of the URL. Use an ampersand (&autoplay=1) if this is not the only parameter.
http://www.youtube.com/embed/Video ID?autoplay=1
Loop Video
There are many online websites offering this functionality (often involving just changing the domain name), but there is no need to use an external service because YouTube actually has this built in.
Same procedure as using the large player, but add ?loop=1. Use an ampersand (&loop=1) if this is not the only parameter. This is very useful for looping music.
http://www.youtube.com/v/Video ID?loop=1
Embedding Videos URL Tricks
The video URL in the source code for embedded YouTube videos also allows for various query string parameters in addition to the ones provided by YouTube in the embed video options.
Video-ID is a placeholder for the YouTube video ID which is the string of alphanumeric characters after the watch?v=.
Start the parameter string using a ? question mark. Then, use an ampersand & to connect additional parameters. An example parameter would be http://www.youtube.com/embed/VIDEO-ID?modestbranding=1&rel=0.
Since this is HTML, all ampersands must be replaced with & or it won't be validated markup.
For these examples, replace PARAMETER with the provided parameters (excluding the ampersands). Highlighted lines show where changes are needed.

</object>
For the new iframe embed method, its easier since there is only one URL.
<iframe width="560" height="349" src="http://www.youtube.com/embed/VIDEOID?PARAMETER&PARAMETER2" frameborder="0" allowfullscreen></iframe>
Embed High Quality Videos
Add the following parameters to embed a higher quality video:
&vq=small – 240p
&vq=medium – 360p
&vq=large – 480p
&vq=hd720 – 720p
Of course, if the quality is not available, this parameter won't do anything.
Autoplay
By default, embedded videos do not autoplay. If you want the videos to autoplay, simply add &autoplay=1 to the URL.
Auto Loop
If you want your videos to automatically loop, simply add &loop=1.
Hide Search Box
Want to prevent users from searching for other videos on your embedded video? Simply add &showsearch=0 to the end of the URLs, which currently appear twice in the standard embed code.
Disable Related Videos
By default, YouTube videos show links to several related videos at the end. However, this might be videos of your competitors and you certainly don't want that. To turn off related videos, add &rel=0.
No Related Videos
This embedded video does not show any related videos thanks to a parameter.
Remove YouTube Branding
You can now remove the YouTube branding from the video. This can make videos look more professional. Add the parameter ?modestbranding=1.
So your code will look like this:
<iframe width="560" height="349" src="http://www.youtube.com/embed/VIDEOID?modestbranding=1&rel=0" frameborder="0" allowfullscreen></iframe>
For removing the branding, this parameter should be first or it might not work properly.
Here is a video using the embed URL with the YouTube logo removed and related videos disabled.
Remove Title
When a user hovers over an embedded video, the title of the video shows. This also serves as a link back to the video page on YouTube. If you want to hide it, use the parameter ?showinfo=0.
Note that this does NOT work with removing the YouTube branding. Adding this parameter causes the modestbranding parameter to break.
Disable Backlink
To disable any backlinks to YouTube, add a a parameter allownetworking to the Flash object and set it to internal. This only works on the old embed code. See this comment for more details.
Please note that disabling the backlink may be a violation of Section 4F of the YouTube Terms of Service. Since YouTube is a free service, you should provide this backlink.
Start Video from Specific Point
If you want the embedded video to start from a specific point rather than the beginning, simply add &start=60. The number is in seconds.
Disable Fullscreen
Do you want to prevent your viewers from watching the video in full screen? Configuring this is slightly different from the other options.
In the video URL, toggle both fs=1 to fs=0. Then toggle both AllowFullScreen options to false. This is a total of 4 changes. Your code should look like this.

Update: YouTube has made many changes recently and the fmt parameter does not seem to work anymore. For HD, add &hd=1 instead. The fmt parameter no longer does anything.
This example video link will start automatically in 720p HD (&hd=1).

Skip to Specific Time
Suppose you're trying to share a video clip with someone, but you don't really think its necessary for them to watch the whole thing from the beginning. You can specify where the video should start as well as easily jump to a specific point by adding #t=7m30s. The number in front of the 'm' is the minute and in front of the 's' would be seconds. In this example, I'm skipping to 7:30.
This example video link will automatically skip to 1:32 (#t=1m32s).

Browser Window Full Size Player
This will load a large player that fills your entire browser window.
Simply replace the '?' and '?=' in the URL to '/' and remove 'watch'.
http://www.youtube.com/embed/Video ID
This example video will start in a full size player.
Prevent Video from Autoplaying
Same procedure as using the large player. This player does not start playing automatically. If you are using this full size player and want it to autoplay, then simply add ?autoplay=1 to the end of the URL. Use an ampersand (&autoplay=1) if this is not the only parameter.

Loop Video
There are many online websites offering this functionality (often involving just changing the domain name), but there is no need to use an external service because YouTube actually has this built in.
Same procedure as using the large player, but add ?loop=1. Use an ampersand (&loop=1) if this is not the only parameter. This is very useful for looping music.

Embedding Videos URL Tricks
The video URL in the source code for embedded YouTube videos also allows for various query string parameters in addition to the ones provided by YouTube in the embed video options.
Video-ID is a placeholder for the YouTube video ID which is the string of alphanumeric characters after the watch?v=.
Start the parameter string using a ? question mark. Then, use an ampersand & to connect additional parameters. An example parameter would be http://www.youtube.com/embed/VIDEO-ID?modestbranding=1&rel=0.
Since this is HTML, all ampersands must be replaced with & or it won't be validated markup.
For these examples, replace PARAMETER with the provided parameters (excluding the ampersands). Highlighted lines show where changes are needed.

For the new iframe embed method, its easier since there is only one URL.
<iframe width="560" height="349" src="http://www.youtube.com/embed/VIDEOID?PARAMETER&PARAMETER2" frameborder="0" allowfullscreen></iframe>
Embed High Quality Videos
Add the following parameters to embed a higher quality video:
&vq=small – 240p
&vq=medium – 360p
&vq=large – 480p
&vq=hd720 – 720p
Of course, if the quality is not available, this parameter won't do anything.
Autoplay
By default, embedded videos do not autoplay. If you want the videos to autoplay, simply add &autoplay=1 to the URL.
Auto Loop
If you want your videos to automatically loop, simply add &loop=1.
Hide Search Box
Want to prevent users from searching for other videos on your embedded video? Simply add &showsearch=0 to the end of the URLs, which currently appear twice in the standard embed code.
Disable Related Videos
By default, YouTube videos show links to several related videos at the end. However, this might be videos of your competitors and you certainly don't want that. To turn off related videos, add &rel=0.
No Related Videos
This embedded video does not show any related videos thanks to a parameter.
Remove YouTube Branding
You can now remove the YouTube branding from the video. This can make videos look more professional. Add the parameter ?modestbranding=1.
So your code will look like this:
<iframe width="560" height="349" src="http://www.youtube.com/embed/VIDEOID?modestbranding=1&rel=0" frameborder="0" allowfullscreen></iframe>
For removing the branding, this parameter should be first or it might not work properly.
Here is a video using the embed URL with the YouTube logo removed and related videos disabled.
Remove Title
When a user hovers over an embedded video, the title of the video shows. This also serves as a link back to the video page on YouTube. If you want to hide it, use the parameter ?showinfo=0.
Note that this does NOT work with removing the YouTube branding. Adding this parameter causes the modestbranding parameter to break.
Disable Backlink
To disable any backlinks to YouTube, add a a parameter allownetworking to the Flash object and set it to internal. This only works on the old embed code. See this comment for more details.
Please note that disabling the backlink may be a violation of Section 4F of the YouTube Terms of Service. Since YouTube is a free service, you should provide this backlink.
Start Video from Specific Point
If you want the embedded video to start from a specific point rather than the beginning, simply add &start=60. The number is in seconds.
Disable Fullscreen
Do you want to prevent your viewers from watching the video in full screen? Configuring this is slightly different from the other options.
In the video URL, toggle both fs=1 to fs=0. Then toggle both AllowFullScreen options to false. This is a total of 4 changes. Your code should look like this.
