I am a Mac user and I recently decided to put some files from one of my older computer's onto my new one by usb drive. I noticed when I was in the terminal all the files were labeled red and are normally supposed to be grey.
Any idea what might be the cause of this?
Here is an example picture.

TL;DR: I have a small internal hard drive and a 2TB iCloud Drive. I want to have access to all my files (iCloud), but I don't want all of my files on my computer.
In macOS (since Sierra I believe) Apple included a features where you can have your Desktop and Documents folders synced to in iCloud Drive, and if you enable it, when your drive fills up, macOS removes local copies of those files and replace it with a little placeholder.
I'm wonder if there is a way to pick and choose what files get offloaded to iCloud this way and when. Let's say I just added a file to my Documents folder that I want to keep, but I have no intention to use it for a while, so I just want it to sync to iCloud then replace the local copy with the placeholder, instead of waiting for my drive to fill up and then have macOS auto offload files for me.
Also, it would be nice to have more than just Documents and Desktop offloadable, but I'm guessing Apple doesn't expose that much functionality in their SDK that I could write an app to do that.
I currently don't develop in any Apple approved languages (Swift & Obj-C) but if there is a way to create an app with this ability to offload files to iCloud Drive I'll deep dive into the language to scratch this itch.
Note: I know I can store any file I want in iCloud Drive by dragging a file into the iCloud Drive icon in the Finder, but to my understanding, these files require a local cache of the file and not this placeholder method that Documents and Desktop folder syncing uses. If there is a way to offload through the customer facing iCloud Drive access in the Finder I'm open to that method too.
Within macOS Catalina this can now be done by right clicking the file/folder and clicking "Remove Download"
For those who cannot upgrade to macOS Catalina, you can simply turn off the iCloud drive in system preferences and then manually upload and download your files via icloud.com. May seem a little tedious, but doing things this way is intuitive enough that you shouldn't make any mistakes moving/locating your files.
I have written a Windows thumbnail handler for specific file types. I have two pc's running Windows 7 Enterprise. On one pc everything goes well. On the other pc, the thumbnail generation works only when there is no program associated with the file extension. In that case the thumbnail generation is taken over by the associated program (I see an icon). Changing the associated program (e.g. to Notepad++) changes the icon. I suspect this to be a registry setting, or a folder view option, but I have no idea where to start looking.
Answers appreciated.
I have accidentally deleted the file System/Library/Extensions/IOStorageFamily.kext by mistake. I know how stupid this was!
Now my iMac (model 2008, running Mavericks) gets stuck on the grey startup screen and hangs forever after the Apple logo turns into a no entry sign whilst the wheel continues to turn forever, see the following link for image showing this screen:
No entry sign on startup screen
I have run Disk Utility from the install CD and repaired the disk permissions with no success.
I have tried to run the rescue partition by using the Command + R key but this just displays my exsisting HD and does not show another option.
I have tried to boot into single user start with no success. The screen eventually hangs and says it can not find IOStorageFamily.kext.
I have tried to boot into safe mode with no success. It simply fails with the no entry sign as above.
I have reset the PRAM but this did not make any difference.
I have done a hardware test using the D key on startup but this returned no errors.
Please can someone advise if there is any way to fix this problem and if the is then what is the best way to do it? I know that it is not a harddrive failing or anything else and is simply because I accidently deleted the IOStorageFamily.kext file. Surely there is a way to repair this?
I appreciate any help or advice.
Many thanks
I have managed to fix the problem by using the following method:
http://support.apple.com/kb/PH13842
It says:
If you have two Mac computers with FireWire or Thunderbolt ports, you
can connect them so that one of them appears as an external hard disk
on the other. This is called “target disk mode.”
Connect the two computers with a FireWire or Thunderbolt cable. Start
up the computer to be used as a disk in target disk mode: If the
computer is off, start it up while holding down the T key.
If the computer is on, choose Apple menu > System Preferences, click
Startup Disk, then click Target Disk Mode.
When the computer has started up, a disk icon appears on the desktop
of the other computer.
Transfer files by dragging them to and from the disk. Eject the disk
by dragging its icon to the Trash. While you drag, the Trash icon
changes to an Eject icon.
On the computer you used as a disk, push the power button to shut it
down, then disconnect the cable.
After connecting to another Mac I simply copied the deleted file back into the correct directory from the host Mac.
I then booted my Mac successfully and repaired the file permissions via Disk Utility.
I'm working on a device that writes some information directly to a flash drive, without using any file system (it just writes blocks of data directly to the disk sectors). After the flash drive is filled, I need to plug it into any computer with windows and read data using my application.
Everything works great except for when I plug the flash drive in windows warns me that flash drive is invalid an offers me to format it. I want to get rid of this message for my flash drives on any computer that have installed my windows application.
My flash drive have signature bytes at the start so I can always make out whether it's my flash drive or just a regular flash drive.
My idea is that I should be able to write some sort of service or driver which will check all flash drives and will disallow OS to mount my drives. However I don't know whether its really possible and I can't find any documents mentioning this sort of functionality.
I'd appreciate any docs / links / functions names that can help me suppress unformatted disk warning.
Make a tiny real partition at the start and format it to keep windows happy.
Then just use the rest of the drive as you please
This seems to work:
Remove the drive letter assigned to the device:
Right-click the 'Computer' (or 'My Computer') icon on your desktop or in the Start Menu and select Manage. The 'Computer Management' window should appear.
From the list on the left, select 'Disk Management' (within the Storage sub-tree).
Right-click the encrypted partition/device and select Change Drive Letter and Paths.
Click Remove.
If Windows prompts you to confirm the action, click OK.
I need to have a flash file be opened and viewed from a USB automatically on both Win and Mac.
I read about various solutions depending on the format of the flash output:
autorun.inf if Flash published as exe(Win)/app(Mac)) which seems to be working only on Win;
html embedding if Flash is published as swf, but this turns into a problem of launching html file.
What is the best known practice/solution?
For the PC, you can use an autorun script. On the Mac, there is no such feature (thankfully). What you can do on the Mac is have the Mac partition open, and using a background image, display instructions to "click here to start", or whatever other verbiage you desire, pointing to your Flash Projector file.
will this help ?
