Couldn’t erase anything, reformat, reinstall any new copy or backup except of Catalina over and over again. Issue 2: Couldn’t force a reformat or erase of my MacOSX CatalinaĮverything was locked. I detached everything, headed into Internet Recovery, and used that Time Machine backup I created to then reinstall my old MacBook before the upgrade. I booted from the Carbon Copy Clone of my hard drive from when it was still Mavericks using my external harddrive, and then used a second external hard drive to Time Machine clone that drive. The only thing that saved me, was that I had a Carbon Copy Clone of my MacOSX on my hard drive which is why I am highly recommending you all buy a copy of it. I hate paying for subscriptions and will happily fork over money for software I can use for the next 5-8 years, ONCE, rather than pay monthly. I am not going to Catalina because then my Mac OSX Office Suite 2011 no longer works, and I am not about to buy a 365 Office suite subscription until I am FORCED TO.

Then, you take that Time Machine backup and when you want to reinstall on your actual laptop drive, you select that external hard drive. There, you can actually attach a second hard drive now, and use it as a Time Machine backup of your booted Carbon Copy Cloned drive. To boot up from this external Carbon Copy Cloned drive, go into Settings > Restart > Select the external drive How to boot up from an external Carbon Copy Cloned drive This means my laptop could die, and because I have a bootable copy of my entire laptop, I live with zero fear that I could attach the external drive copy to one of my other MacBooks and access all my data and run it as if I had my old laptop. This may not seem very exciting to you unless you’re also a business owner like me who keeps a separate business laptop and lives in fear of not being able to access years of data and bookkeeping especially come tax time.Īt any rate, even if you don’t run a business but your MacBook completely goes black and dies a painful death, you can still use any other Mac you have available to borrow or WHATEVER, boot up from this Carbon Copy Clone drive, and work off it / use it to overwrite the other Mac you have and use it as your new Mac. It basically creates a bootable Mac, and you can literally use that hard drive clone to plug into ANY Mac, boot off it and WORK ON IT if you wanted, as if you have two Macs. Back up every month at least if not more often.Have two hard drives dedicated to backing up.Would be easier to ALSO keep a Time Machine backup in parallel but not necessary unless required because you can use CCC and create a Time Machine backup on the fly.Always keep a current-is copy of your Mac with Carbon Copy Cloner (monthly in my case).Carbon Copy Cloner – I purchased this software and it is fantastic.Time Machine – Free with your MacBook but has limitations.You absolutely need to have two things if you are a Mac user: This is unusual for my blog to post but I am doing it in the hopes that it helps someone else save 3 days of frustration. What hasn’t helped, are all of these tech-y articles online telling me THE SAME THING over and over again for my issues that I ran across when leaping so far. I am talking 6 leaps in upgrades here, taking advantage of the time I have to get this all done. In the past week I have been trying to upgrade my MacOSX from Mountain Lion (which no longer exists even as a download) to High Sierra.
