Windows' Disk Management has overwritten the GUID partition table with something unknown. This usually only effects the partition table but not the content of your disk (though it seems to be gone)! A proper GUID partition table has to be restored. The particular obstacle here is: the OP neither has a thumb drive nor a second Mac. Preparation: Backup the ...

Part of the issue is that low priority I/O now seems to get throttled heavily (or so fs_usage tells me - if you run fs_usage and look for backupd, you can see it getting throttled). So if you have a ton of files, just the time it takes to do the i/o takes forever, even if the files are small (because it performs a bunch more i/o operations around xattrs/etc ...

It is possible to create a Logical Volume Group spanning over more than two disks. I doubt that it will differentiate between fast and slow HDD. The SSD part should work though. To accomplish this put all drives in your iMac and boot to a Mavericks or Yosemite bootable installer thumb drive. Partition all drives as simple volumes with Disk Utility. Then ...

You must have enabled FileVault, therefore your disk this encrypted, you go to: System preferences / security and privacy / FileVault. if enabled it so you disable, it should take some time why he will decrypt your disk, then restart and everything returns to normal. for more information: https://support.apple.com/en-us/HT204156

If the hard drive is not encrypted, then it's not at all secure! Basically anybody can take the hard disk, put it into an external enclosure and connect it to another Mac to read all files on the disk.

If you have your data safely backed up or don't care about losing it, you can follow these instructions to recreate your Fusion Drive. Boot into Internet Recovery or an OS X bootable drive. From the Utilities menu, open Terminal. Run diskutil cs delete 654B2807-197B-46D1-9919-B75C0290D33A to destroy your current Fusion Drive. This WILL lose all of your ...

You can use an external hard disk formatted with HFS+ as a Time Machine target for several Macs without problems. Time Machine itself will make sure that the data is not getting mixed up by using the name of each Mac as part of the path.

This was (or obviously still is in VirtualBox 5?) a known bug of VirtualBox 3 which should have been fixed in 4.0.0! The workaround is disabling the use of the new async I/O code... done by ticking "Use host I/O cache" for the SATA (and SCSI) controllers.

There's no such thing as "Built for Snow Leopard". That labeling just an old habit PC manufacturers have for Windows, but it doesn't apply to Macs at all. If Apple lets you run the OS, that means they tested it, and should work just fine. The reason you can't resize those disks is because they are formatted as "ExFAT", and OS X doesn't support resizing ExFAT ...

From help.cleverfiles.com How to Uninstall Disk Drill What’s the correct way to uninstall all the components of Disk Drill? Usually, a Mac user will just move an app to the Trash, and consider the job done. But Disk Drill installs some low-core modules for effective data protection and recovery. So for this type of system-level software, dragging the app ...

There is an application that comes with your Mac (in /Applications/Utilities) called Boot Camp Assistant. Launch that and follow the instructions provided on screen. I am guessing that you have a disk image file of the Windows installer on your computer. If you double-click on it it will open up into a virtual hard drive. If that is the case Boot Camp ...

Bad drive cable I finally took this to an apple store, and the techs diagnosed it as a bad drive cable - a common problem for Macbooks from that year, they said. With a new cable, the Recovery Mode installation worked, the El Capitan upgrade worked, and the machine has been running smoothly for a week.

Folder with the question mark usually means "no valid device to boot from". Try to boot to recovery (if any exists) by keeping pressing command + r when turning on the Mac. You should be able to reinstall it there. If still fails you may try Mac OS X internet recovery (cmd+option+r keeps pressed while pressing power button) If still fails, get someone ...

Update for El Capitan, see the attached screen shot from Disk Utility's Info-window.

Long story short: the white drive represents a "removable disk", and the orange drive represents an "external disk". Think of a removable disk like a thumbdrive, something small that people would usually throw in their pockets or carry around on a regular basis, or in your case, an external SSD. An external disk is usually the exact opposite of the ...

If you make two different partitions in the external HD, you can easily have the two different Time Machine backup in the each partition. You only need to specify the partition to use for the MacBook during the initial Time Machine setup. Then the Mac would know which partition to use for its backup the next time you connect the external HD. The same goes ...
