Chosen Solution
Hey guys, So a month or so ago I replaced my HDD with a 120GB SANDISK SSD; wiped the original HDD and housed itin the optical bay; upgraded to 16GB RAM and did a clean install of the OS (now 10.10.3) Since then, everythings been running like a dream and I’ve been bragging to everyone about how it’s like getting a brand new MacBook for a couple hundred quid. Suddenly though, everythings running super slowly, I get the spinning wheel of death every 5 seconds and it can’t handle doing anything. This happened literally over night, out of the blue… So far I’ve tried verifying both disks (all ok) and PRMC reset, which seemed ok. Neither helped… I have my final paper due in a week, pretty terrible timing - can anyone help? Thanks
Do you have a bootable external disk which you can boot up with? If you do do that and run Disk Utility fixing the permissions & drive. But before you do make sure you have copies for your work just in case! Last thing here is to go to the Startup control panel and make sure the correct disk is selected.
Replace the HD/IR cable with a new 2012 cable.
