Hey guys, will I be able to put Mojave in my 2009 MacPro 5.1 ? I am just looking ahead at this time. I am on Sierra and happy to stay with that.If so what will I need to do, thanks !

Is your GPU Metal Graphics compatible? If so, you’ll be fine. The stock card in a 2009 will not be but there are those you can buy that are.

Since you indicate your 2009 (started life as a 4,1) is a 5,1, I assume you did the firmware update at some point. That's point 1.

2. You will need a Mac EFI GPU (GT120, ATI5770 etc) to move from Sierra to High Sierra, which is required before moving to Mojave. You must do the full 10.13.6 install to be sure your Mac gets the required High Sierra firmware update.

3. Once on High Sierra 13.6, you will need to replace the Mac EFI GPU (remove it from your Mac!) with a Metal-compatible card before installing Mojave. Another firmware update will be performed when installing. Least expensive Apple-approved available as new Metal GPU is this one: https://www.amazon.com/gp/product/B072J ... d_i=284822

The real question: To what extent will any gains realized in moving to Mojave be offset by losses? Like you, I am currently running Sierra. Experimentation with a spare boot drive will be required before committing to Mojave.

Thanks guys. I am always very careful not to move unless I really need to. I am happy to stay on Sierra.Not worth the terror! Just looking ahead for when I really need to do this.

I wouldn't go near it.

Reports that things like JetBrains IDE's are running at about half their normal speed imply that the Java Virtual Machine is not liking Mojave. There is a huge list of apps that still need updating to work - many I use daily.

If it ain't broke, don't fix it.

Oracle did release a new build the day that 10.14 was released.

This review has the usual number of mistakes and opinions masquerading as fact but is generally there.

The most glaring is that the Java 6 runtime does work if you download the 2017-001. Finale 2012–2014.5 works after it is installed if the app was already there or you brought it in via Migration Assistant. Next year, it will no longer be an issue.

If running a lot of 32 bit apps and plugins and cannot upgrade, probably best to stay put.

Also, plan to turn it into a legacy machine sometime in the next year or two and shop for something that accesses the internet. Apple will likely discontinue security updates for El Cap early next year and Sierra in 2020. If you've not noticed that they do this a little after AppleCare (3 years) runs out on the last machine sold that shipped with a particular OS, not a bad idea to pay attention.

The internet is changing. Many of the big things announced for 1/1/2017 are finally happening in regards to Java and Flash support. I log into 50–100 public sites a week and the States are finally catching up—even Michigan (until last month, I had to use FireFox with a weird set of plugins to navigate that site).

One solution is to clone your boot drive and try Mojave on the clone.
That way you can test all of your stuff with little risk.
