My current MacBook Pro has the OS X El Capitan. Actually, I have multiple MacBook Pros, I only buy newer versions when I think I have to upgrade my device.
Learned my lesson by being Apple's guinea pig and upgrading without a patch release. This time I won't forget to backup via Time Machine, it's just the smart thing to do. Gonna see how the Mojave patch will fix things before I decide to upgrade. Shockingly, I am not a fan of how Mojave drains my battery it's a bit of a deal breaker. This leads me to my review of macOS Mojave. Hope this helps others who are looking to downgrade the OS on their Mac. The last step will have you enter in WiFi credentials that will be used to download the version of macOS / OS X that came pre-installed, or the closest version still available. Boot machine while hold down Shift-Option-Command (⌘)-R.Use Disk Utility to erase your current partition.Start machine while holding down Command (⌘)-R to enter Recovery Mode.I used rsync to transfer files to my old MBP before staring the process Back up files to another machine, an external hard drive, or a separate partition.Basic idea: format your OS partition and download the OS your Mac came with (or the closest version available). I recommend reading the guide for the OS you want to downgrade before proceeding to the next section. MacOS High Sierra won't install on top of a later version of macOS, but you can erase your disk first or install on another disk. These guides are hidden on the Apple Support Site and you have to read the fine print before it all makes sense: I followed the instructions and a few hours later all my problems were gone. While backing up my data, I found an article on the Apple Support site titled: How to upgrade to macOS High Sierra.Ī better title would be: "How to downgrade to macOS High Sierra". I waved the white flag and set up a Genius Bar appointment. Was the problem Mojave? Was it my battery? Posts on Apple Forums and Reddit pointed the finger at Mojave, but I couldn't confirm because Apple makes it hard to downgrade the OS. I was only able to squeeze 2-3 hours of battery for each full charge well below the 10 hours promised in Apple marketing, which we all know is 5-8 hours in developer time. I lost a week of productivity setting up the machine and then troubleshooting battery issues: my week-old MacBook was constantly working with the fan on. It's a huge step up from my late-2013 model ~6x according to Moore's Law.Īs soon as I opened the box, I upgrade from High Sierra to Mojave. Purchased the 13" Touchbar with (mostly) maxed out components: 2.7GHz i7, 16GB RAM, and 1TB SSD.
I started a new job in October and bought a 2018 MacBook Pro to celebrate.
