I'm an elderly woman who is partially blind.

One thing you missed is that you do not need an operating system on you new drive before using ccc to clone to a new drive. So I switch to a USB 3.0 external drive which gives me great performance. At first, I tried my usb 2.0 external drive. Performance is much improved over my rotating internal drive. I'm running an SSD off of an external drive. They will be able to advise you on which external drive for you machine will give you the best performance. I would get an external ssd drive and use the current drive as backup. I'd recommend a second drive as a backup. Have him look over the instructions and see if it is within his skill set. Your friend should have experience working with pc laptops. The iMacs are rather tedious to disassemble and re-assemble. I understand you are running off of an external drive now. If you have advice, I'm grateful.Ĭlone (Carbon Copy Cloner) my current working OS - I'm booting into it on a peripheral drive Will this even work? 1) Have a OS ready on the new internal drive, 2) clone (Carbon Copy Cloner) my current working OS - I'm booting into it on a peripheral drive - over the new OS on the new drive. Do I have to borrow a dvd player and burn a disk, and use the dvd player for an install - or is it good enough to have the dmg on my current peripheral drive? There's a 20$$ Mountain Lion OS in the Apple mac store, but I don't for sure know how to install it on the iMac - the Mountain Lion OS is a download. Most of my important apps and games aren't compatible after High Sierra. If I do (I think) I won't be able to clone my current OS (High Sierra) backwards over it. My problem is: How to get a functioning OS on the new drive so I can clone my old drive onto it. I did find a step by step guide on iFixit and have a friend with tools and nimbler fingers than mine. I know almost nothing about computer repair.
