On Monday, September 24th Apple will be releasing macOS Mojave. The newest Mac operating system’s release follows an already busy week for Apple — new iPhone XS and XS Max, Apple Watch Series 4, watchOS 5 and iOS 12. Unlike the major file system change last year with macOS High Sierra, there does not appear to be a significant number of changes to the infrastructure of the operating system this year. However, I still recommend you wait to update your computers to macOS Mojave.
Why wait to install macOS Mojave
Personally, I love Apple’s software. There is something about the simplicity and integration within the ecosystem that makes me a fan. This years macOS Mojave is no different. I can’t wait to use features like Dark Mode, Stacks, Continuity Camera, group FaceTime, Apple News and HomeKit. However, I have also come to the realization that being an early adopter may not always be a good idea. Especially for installing any new versions of macOS on a business critical machine. Let me explain.
Over the course of the last few years, the macOS operating systems Apple has released have not gone as smooth as the company probably would have liked. Last years major change to an APFS file system caused a lot of installation issues with macOS High Sierra. Repartitioning hard drives and erasing the computer for a reinstall were consistently needed to fix failed installations. Eventually updates were finally released to resolve the issues but please be aware, these needed fixes meant your data was lost if you did not have a backup. If you did have a backup, you were fortunate only to have to endure hours of downtime while the issue was resolved.
Other potential pitfalls of being an early adopter of macOS can be incompatible software, instability within the system, or security holes not yet identified. Imagine waiting for a bug fix for weeks while you are having performance issues or critical security gaps on your Mac. Does that sound like a productive and efficient work environment? Probably not.
While this years version of macOS Mojave doesn’t have the major changes to the file structure like last years macOS High Sierra, please proceed with caution. If you want to go for it anyway, here are a few recommendations before you download and install the new software.
The installation of macOS Mojave will work on a variety of older models. A good rule of thumb here, if your computer is a 2012 model or newer, then you should have no problem installing the operating system. There are unique requirements for MacBook and Mac Pro, so if you have one of those, check out Apple’s support page here.
Check Storage Space
Reading Apple’s site, it states that “the space required to install macOS Mojave is still being determined, but 20GB of storage space should be more than enough.” I don’t know about you, but that does give me some pause if they can’t tell me how big the files are a few days before release. Hence why maybe waiting is a good idea.
Make a Backup
Always, always, always…repeat after me…always backup a computer before doing a software upgrade or even an update that will require a reboot. You can check out my guide on using Time Machine if you need help. You can find that here.
If you have the time or the will, before installing any new major upgrade to an operating system I recommend giving your machine a tune-up too. Macs are fairly well maintained by the operating system themselves, but us humans, we abuse them from time to time with downloads, website data, software installs, etc. that can make the machine a little bloated and slow. So start your new macOS installation off on the right foot. What I use and my personal recommendation is CleanMyMac X by MacPaw.
