Hey Guys, I have a bit of a problem with my 2009 27” iMac. It has been shutting down halfway through botting up. I then booted into recovery mode and was able to do a clean OS install on the iMac then booted up no problem. Then as I use it, the iMac just freezes (but the mouse still works) and I won’t be able to do anything until I force reboot it. Sometimes, there are some graphic distortions onscreen (only during boot up), could this be due to overheating? I’m considering changing out the SSD as this might be the problem? Any suggestions would be much appreciated! Thanks
OK, I see the problem! Here’s the spec sheet for this drive: Intel 510 Series SSD Product Specification This is a fixed speed SATA III (6.0 Gb/s) SSD, your system can only support SATA II (3.0 Gb/s) drives! This drive is too fast for your system! You would need a SSD which is either a fixed SATA II (3.0 Gb/s) drive or an auto sense drive like the Samsung 860 EVO which is able to sense the systems I/O speed and match it. We can see this by looking at the spec sheet where the Interface line tells us: SATA 6 Gbps Interface, compatible with SATA 3 Gbps & 1.5 Gbps interfaces So you will need to replace the Intel drive with another drive, and you want to review the drives spec sheet to make sure it offers support for SATA II (3.0 Gb/s)
