Hey all...put an Intel SSD in my late '08 MBP and have been experiencing serious issues since...every few minutes or so, it will beachball and be totally unresponsive for a period of a few seconds. It doesn't matter what I'm doing or what applications are open; even with a fresh reboot and only one Safari browser window open, it happens. I often have to work on this machine so it's very irritating. Following others' advice, I enabled TRIM...it seems to have maybe helped a bit, but the issue still persists. I've also been told to try and update the SSD Firmware. Intel mentions something about "TRIM support" with the firmware update, so I'm encouraged that this might resolve my issue...and even if not, it's just a good idea to have the latest firmware. I downloaded the .iso from Intel's site. Apparently you are meant to put this on a DVD-R or thumb drive and boot from it, and it will update the SSD firmware. I actually couldn't even clone the .iso onto a thumb drive with Disk Utility, and instead had to do it on a Windows machine...but I eventually got that far at least. I confirmed that the thumb drive has the boot partition as it should. But when I reboot holding "option", the thumb drive does not show up as a bootable volume...so I'm kinda dead in the water. Has anyone found a resolution to this? Next step is to pull out the SSD and connect it to a Windows machine as an external, then try to install it that way (assuming Windows will boot from the .iso), then put it back in my Mac. I feel like there really has to be an easier way...does Intel just not bother supporting Macs with firmware updates? It seems that OSX (logically enough) won't register a volume as bootable unless it actually has a copy of OSX on it. Makes sense, but it's hampering my efforts here. Intel's site lists this update as OSX-compatible, but doesn't really post any instructions. And trolling various forums I see many, many others are having the same issue. Thanks in advance.
