The information page from the app store states that I need to have OSx 10.8 or later. I am currently using High Sierra and my version is 10.13.6 I would imagine my version is later than the minimum requirement but when I try to download Mojave it says my system is incompatible. Any ideas???

Which Mac do you have? Model and year? It's not the version of macOS you currently are using that determines whether or not you can install Mojave, it's the model and year of your Mac that is the determining factor.

iMac (21.5-inch, Mid 2010) - I'm guessing by the date it's not going to be compatible. I assumed that when it asked for minimum version requirements that's exactly what it meant.

There are some exceptions, but generally, you need a Mac introduced in mid to late 2012 to be compatible with 10.14 Mojave. An iMac needs to be a Late 2012 for Mojave.

If you want to play around with Mojave anyway, then it is possible with a patcher app like "DOSDude"

According to that page, when running from Mojave, the graphics is almost unusable on that iMac model.

Thanks for your help, I really appreciate it. I guess I should upgrade but I like my Mac with the integrated disc player/reader. I don't think the recent Macs have them anymore.

That's your choice of course, however, my last two iMacs did not have an optical drive. I have two external optical drives that I use and find them to be adequate for those times when they are needed. Apple internal optical drives are troublesome in that they break very easily which makes me happy that they are no longer included.

High Sierra should continue to receive security updates for the next few years so you don't need to buy a new iMac right away. Unfortunately Apple does not announce when they discontinue security updates for older macOS releases but the community has generally found it to be around three years after their initial release. Since macOS High Sierra was released a year ago, it'll likely continue to receive security updates until the summer of 2020. Not guaranteed though.

As a guideline, OS X El Capitan (version 10.11) was initially released in September 2015 and last received a security update in July 2018 and is probably the last security update it will receive. Likewise, OS X Yosemite (version 10.10) was initially released in October 2014 and last received a security update in Jul 2017. As you can see, there is a pattern of just under three years before Apple quietly stops support for older releases.

As chscag mentioned, you can always buy an external disc player that plugs into an iMac via an available USB port if when you upgrade to a newer iMac, you still need to use disc media once in a while. It's just obviously an extra expense to consider when you think about upgrading.

[doublepost=1539023535][/doublepost]Thankyou, I did not know about this. Very helpful! The optical drive issue is something that has put me off getting a new Mac as I like the built in one. I may have to bite the bullet in the future.

Optical drives nowadays are a non issue since external units are inexpensive and work well. When was the last time you needed a floppy disk drive? LOL. :rolleyes:

Don't sweat it. This OS from Hell bricked my 2015 2.5 GHz I5 (16 gb RAM) by deleting all account passwords.

Probably depends more on the amount of available RAM. When I bought my MacBook Pro in 2015, I immediately upgraded it to 16 Gb from the stock 4 gb to improve performance. Unfortunately, upgrading to Mojave erased my login passwords, so no account worked and I had a brick. Re-installed High Sierra from backup to regain functionality.

Nope. Refer to post #2. His machine is too old to install Mojave. His 2010 model does not support "Metal" and that's one of the requirements set by Apple. Available memory has nothing to do with it.
