So, just to be clear, you replaced the optical drive in your iMac with an SSD and I am assuming a drive caddy. In the process, you removed the optical drive temperature sensor: When this sensor is absent, the fans will spin up to full speed. This is the "fail safe." So, you are using a software utility to control the fan and essentially override the ...

I'm afraid not. It is hardware-dependent, not software. The earliest model to support Target Display Mode was the Late 2009 iMac. See : Use your iMac as a display with Target Display Mode

At least 2, and likely no more. The Retina 5K iMac can support an external 4K (UHD) (3840x2160 @60Hz) monitor AND a second external monitor up to at least 1920x1200 (60Hz) at the same time. This is the setup I am currently using. No special tricks needed. Machine: Core i5 3.5 GHz, Radeon R9 M295X 4GB VRAM graphics card (BTO upgrade), 16 GB RAM, Yosemite ...

I would encourage you to download etrecheck: http://www.etresoft.com/etrecheck Then in Etrecheck, you will see files & programs that slow down or crash your mac.

I would suggest, that assuming you can physically--and safely(!), taking note of the comment about voltages and CRTs--removing the hard drive and taking it apart. Most times you can get the actual platters/discs out without too much trouble and carefully smash them. Most are, I think, a metal coating on glass of some sort, so watch splinters wear eye ...

You can move the folder to another drive, then use a symbolic link back to the original location, so iTunes can still find it. A symbolic link is a bit like a shortcut or alias, that the system can use to target a file or folder in another location. Because of the rather arcane method you'd nee to employ in Terminal to generate them, I've always used a ...

There may be a piece of commercial software that can intercept a call to reboot/shutdown however I do not know what it is, if it exists. My suggestion, despite you editing out the issue in your OP, is to fix the issue and not look for a workaround! That said, I give you a workaround that you certainly can test and it should prevent a software call to ...

When the Bluetooth device is connected, press ALT/OPTION and click the Bluetooth icon. When you select the device in the list you will see a Remove option that should stop if from connecting in future.

If you have bootcamp installed, i would recommend running the Magician tool provided by Samsung there. Works like a charm and much more intuitive than working with the bootable usb drive or a bootable dvd method. The Magician software also checks if you need to do any additional things other than updating the firmware, so it could save you a lot of time. I ...

I faced the same situation and found that my colleague uses Notifyr app (http://www.getnotifyr.com/) which runs with bluetooth connection. I asked him to stop using the app, the problem seems to be solved in these two days.

Here's the solution that worked for me (YMMV): Turn off bluetooth Reboot your mac Put your bluetooth devices in "discoverable" mode Turn bluetooth back on You should be able to see / connect to your devices in System Preferences > Bluetooth now.

Apparently it's possible to enable MAC filtering using the Internet Sharing feature in Snow Leopard. Here is an extended description how to do it and at the same time overcome some flaws of the sharing implementation of SL. Essentially you have to add an additional key/array in the /etc/bootpd.plist containing the MAC as string: .... ...

As you write, Apple seems to have undertaken some effort to make replacement of the internal HDD difficult, as described here: For the main 3.5″ SATA hard drive bay in the new 2011 machines, Apple has altered the SATA power connector itself from a standard 4-wire power configuration to a 7-wire configuration. Hard drive temperature control is regulated ...

The iMac 21.5" Mid 2011 shipped with "500 GB, 1, or 2 TB (7200-rpm SATA) and/or 256 GB (SSD)" Storage and its Hard Drive Interface is "6.0 Gbps Serial ATA (SATA)". So any normal 6.0 Gbps SATA SSD should work. As an example, from Crucial, Apple iMac (21.5 and 27-inch, Mid 2011) compatible upgrades

The short answer is – yes, you can. The not-so-short answer is, it's messy. You can't downgrade, according to all the problems I had with personally trying to. But then I found a working method which I carried out on my own Mac. Sure, it worked, but my Mac is different from yours. It should work, but there's not 'warranty'. As long as you have all your ...

The first pre-installed OS on the iMac14,1/iMac14,2 was Mac OS X 10.8.4. You may install any OS version newer than that one. If you have any personal data on this Mac, save it to an external drive. After creating a bootable thumb drive using the Mavericks installer, boot to the thumb drive, erase the main disk and install Mavericks. Restore your personal ...

Not Necessarily. Check out the article at support.apple.com titled: iMovie '11: Copy or move a project to an external hard disk In particular: Note: To use an external hard disk with iMovie, it must be formatted as Mac OS Extended (Journaled). iMovie doesn’t support network-attached storage or external flash memory drives. I was just surprised (just ...

The issue I was experiencing was due to a firmware lock, likely triggered via iCloud. Because it is a late 2012 model, bypassing the lock is no longer possible by removing a stick of RAM and resetting the PRAM. It is locked-out by an EFI chip that executes the lock routine before booting. My only options er on the side of more extreme hacking (via reflow ...

What I have found out is that TDM (Target Display Mode) on my mid 2010 27" iMac only works with the following resolutions: 720p (1280*720) or lower Native (2560*1440) Any device that tries to output something in between, gets a signal it has to change it's resolution to 1280*720. Many devices can automatically do this (Xbox 360, PS4), but some can not ...

Install a copy of the OS X Server app on a spare Mac with a pile of storage connected to it. Create a share for each Mac that you need to back up, and connect each Mac to its own share. That way, each Mac only sees its own backups. You can also limit the size allowed for each share if you like. Another advantage of having an OS X server on the network is ...

You can backup multiple Mac's to a central Time Capsule. On each Mac: System Preferences > Time Machine > Select Disk. Choose the same Time Capsule for all your computers. Each computer will have a separate .sparsebundle on the Time Capsule disk. When setting up the Time Capsule disk you can set individual accounts which should solve the security issue: ...

You can simply put an Apple Time Capsule in your network and select this as Time Machine backup volume. And you may choose an encrypted backup to ensure more privacy. This works perfect in my office with a dozen MacBooks. A more cost efficient solution may be a 3rd party solution like a Synology DiskStation containing a Raid 1or 5. Synology also offers Time ...

This means the hard drive is encrypted. Boot the machine up, go to System Preferences > Security > FileVault and enter the password to decrypt the volume. EDIT: If you don't have access to the drive/password, force boot to Internet Recovery by holding [CMD] + [OPTION] + [R] and you should see a spinning globe (you'll need to have Internet access).

Viruses or malware do not (generally) cause hard drives to fail. This was asked some time ago - so did you solve the problem in the end and if so, how? For the record: Save the Console log files if this happens again. Using these files it is possible to limit the source of the problem to software or hardware issues. It is rather unlikely that two disks fail ...

I just had the same problem. If I tried to move an icon, it would bounce back. The answer was so simple I couldn't believe it. I went into "View" and clicked on to Sort by "None". Simple. Problem solved.

It depends on what you / your girlfriend wants to do with the iMac. If it is really just used for internet and occasionally watching a movie and listening to music, then an 'entry level' iMac offers more than enough performance. IMHO even an iPad would provide enough performance… We actually use our 5+yr old iMac (Intel Core 2 Duo, 2.66GHz) as a media hub ...
