Use “Delete Immediately” on Files to Bypass Trash in Mac OS X

howapple 发表了文章 • 0 个评论 • 818 次浏览 • 2016-05-11 19:55 • 可能属于这些话题

The latest versions of OS X include a new ability to immediately delete a file or folder from the Mac, bypassing the Trash can. Essentially how the “Delete Immediately” feature works is by circumventing the Trash and rather than waiting for user action to remove the files, it just deletes the file(s) instantaneously from the Mac, making the delete immediately function faster than the typical manner of removing a file in OS X.

Delete Immediately is a handy feature if you want to rid a file or folder from the Mac right away and without having to manually empty the Trash, it effectively skips the Trash function and just deletes the files. This is not intended to be a replacement for secure empty Trash, however and doesn’t offer the same rewrite function.

There are two ways to access and use Delete Immediately in OS X, with a quick access keystroke and from the File menu. 

There is no way to undo this action so only use Delete Immediately if you really truly do want to vanquish a file from the Mac. 

Delete Files Immediately with a Keyboard Shortcut

The quickest way to access the Delete Immediately function in OS X is through a keyboard shortcut:

Select the file(s) or folder(s) you wish to instantly and permanently delete and hit the following keystroke sequence: Option + Command + Delete
Confirm with the dialog that you wish to delete the files permanently and immediately






[Confirm to delete a file immediately in Mac OS X]

This just circumvents placing the files into the Trash, it deletes the file(s) immediately from the Mac. 

Access Delete Immediately from the Finder

You can also access the Delete Immediately option and skip the Trash by using the File menu in the Mac file system:






[Delete immediately in Mac OS X Finder and bypass the Trash]

Select the file(s) or folder(s) you wish to instantly and permanently delete then hold the OPTION key as you access the “File” menu from the Finder
Choose “Delete Immediately” from the File menu
Confirm with the dialog that you wish to delete the files permanently and immediately






[Confirm to delete a file immediately in Mac OS X]

Again, this skips the Trash, and the files are instantly deleted. The same as using the keyboard shortcut.

Similar to using the Trash is that if a file is locked or in use the Trash action will be prevented, and if you encounter a “item can’t be moved” error, you’ll likely need to quit apps and relaunch the Finder first. 显示全部

Fixing an “Item can’t be moved to Trash because item can’t be deleted” Error in Mac OS X

howapple 发表了文章 • 0 个评论 • 707 次浏览 • 2016-05-11 19:53 • 可能属于这些话题

Deleting files and folders from the Mac is usually as simple as dragging the item to remove into the Trash can, but on rare occasions things don’t quite go as planned. One of the more peculiar errors when trying to remove a file appears in the form of the following message when attempting to send something to the Trash; “The item “filename.ext” can’t be moved to the Trash because it can’t be deleted.”


That error message is not exactly descriptive or helpful, but, as it appears to be a bug related to the Finder, the issue is usually fairly easy to resolve by quitting and restarting the Finder. 

There are several ways to accomplish that, the easiest perhaps being the familiar Force Quit shortcut:

Hit Command+Shift+Escape to bring up the Force Quit menu, select Finder and choose “Relaunch”

Option and Right+Clicking the Finder icon in the Dock gives the same option:

[Relaunching Finder]

If you’re a command line user, you can also choose the killall command in the Terminal app.

Whichever approach you go with, be sure to let the Finder completely load again. Then, once the Finder has opened again, you should now be able to remove the file as intended by sending it to the Trash either with a Command+Delete or by dragging and dropping it into the OS X Dock Trash icon. This is fairly basic troubleshooting, but it does work, and has apparently worked to resolve the error for quite some time judging by user responses on Apple forums

Note that if the file in question is locked, you may encounter yet another error now that’s in the Trash can when you go to actually delete the file. If so, that’s also easy to resolve by forcing the Trash to empty whether contents are locked or not. 

In some cases, the inability to trash a file like this is probably a Finder bug, though since it is easy to trigger the message with partially transferred files, it could also be a protective mechanism against prematurely removing files that are partially transferred either through local file sharing or downloading from the internet. Keep that situation in mind if you’re encountering the error message in when trying to trash something from Finder, as it may be resolved by stopping the active file transfer taking place too. 显示全部

How to deal with the "Activation Server Unavailable" error message when restoring an iOS device

Here are the reasons you might get the message that the Activation Server is unavailable:
It really is unavailable. Rare, but it happens. You can check its status here: https://www.apple.com/support/systemstatus/Your antivirus or firewall is blocking access to gs.apple.com. Try temporarily disabling it.Your router's firewall is blocking access to gs.apple.com or to a port that it requires (443).Your phone is jailbroken, or it was at some time in the past.Your computer was used to hack or jailbreak some iOS device in the past (not necessarily the device with the current problem), and its network database was corrupted. Hacking includes using some questionable apps such as recboot, reiboot, Tinyumbrella, redsn0w, etc.
For the last possibility inspect your computer's hosts file. If there are any lines in the file that reference gs.apple.com, that is the explanation. You will need to rebuild the hosts file without those lines. 显示全部
