You'll need to purchase the power adapter for use with FireWire 800 connection.Monterey introduced several new features and changes, including: 'everything Mac', dealer/reseller I purchased my drive from. Not sure where you are from, but I live in the U.S. I just wanted an external drive that would have some modicum of speed improvement over a spinning platter hard drive and I knew there would be a data speed improvement by just,switching/using an externally enclosed, no moving parts, flash memory-based SSD would be any level of improvement. Plus, already having multiple FireWire 800 external mechanical hard drives, they aren't quite as fast as an internal drive. I can't afford to have this drive replaced and installed by a repair center and seeing this is my only work Mac, I did not want to take risk on replacing the internal drive and maybe damage or break something during the whole DIY process.

I got nearly 6 years out of the internal drive. It finally got to the point where the beachball was showing up more and more, intermittent freezes and the occassional shutdown. My late 2009's hard drive has been failing for months, but was dealing with it. I personally have stayed away from Sierra.

I use El Cap for everyday (because of the security updates), and boot into Mountain Lion when I want to run my old Logic Pro and its associated audio hardware, or Aperture (which Apple orphaned on me. This is exactly what I have done because I have some older apps and some older FireWire hardware that is not compatible with El Capitan.

Install Mountain Lion on one, and El Capitan on the other. Format your 1TB internal drive into 2 500GB partitions. If it were me, I would then spring for an additional $30 and buy SuperDuper disc cloning software. This will bring you to 12GB RAM, which is the key (imo). You can buy 8GB of RAM (2 4GB modules) for well under $100.

If not, upgrade your memory from I personally started with 4GB (and therefore had 2 open memory slots). Do I read correctly that you already have 12GB RAM? If so, you're done. Replace the hard drive with a plain vanilla 1TB SATA-3 drive.

As I understand it, you have a bad hard drive. Here's what I would do in your situation. The proc is fine for everything except VMWare Fusion, where it is a little slow but still quite usable. I have a late 2009 running El Capitan and it does fine. Something for you to, at least, think about. I am pretty impressed by its performance!Д«een using this with my 2009 iMac now for about 3 weeks.

I am using an external 480 GB SSD with approx. This enclosed SSD wasn't that cheap, but wasn't all that expensive, either. This is close to a 25% increase in data transfer speeds using an externally enclosed SSD in a FW800 enclosure with a FW800 cable.ДЄnd with no mechanical hard drive, my late 2009 iMac feels pretty quick and snappy running OS X 10.9.5 Mavericks. With the external SSD over FW800, I am averaging about 94-95 MBps with sometimes the data transfer has gone to nearly 100 MBps! is to run your iMac from an externally enclosed FireWire 800 connected SSD ( Solid State Drive).Д«efore the external SSD, I was using a standard hard drive over FW800 and only getting between 70-75 MBps throughput over the FW800 connection. One of the things you can do with your iMac,that I just did, to speed up performance from an external drive.
