GIMP & MacOS 10.12 Sierra

Select this orange download button for Gimp, not the green Torrent button:

The very bottom icon in the Downloads folder icon next to your Trash icon in the Dock will be the downloaded GIMP installer: gimp-2.8.22-x86_64.dmg.

Click this installer once. A new Finder window will appear with just the GIMP application icon.

Open a new Finder window, and click Applications in the Favorites side panel. Now, drag and drop the GIMP application icon into the Applications folder. Find the GIMP 2.8.22 icon on your Desktop, right-click, and eject it.

In your Applications Folder, right-click/control-click/two-finger tap on the GIMP application icon, and choose Open from the secondary menu. The operating system will verify the application for known (by Apple) malware, and then you will receive a new dialog that "GIMP" is from an unidentified developer. Click the Open button on this dialog. At this point GIMP will be performing some internal house-keeping, including building its own font cache from your system. This can be a lengthy process. When it is done, it will pop the application window on screen, and you can begin to use it.

This whole last paragraph is because the application was not downloaded from the Mac Application Store, and would be the normal security process for applications obtained outside of the store. You only have to go through the above ritual once per application obtained in this manner, and subsequent GIMP invocations are a normal double-click, or single click if in the Dock, or from Launchpad.

Hi Cunnla, I am a senior and not very good with technology. Signed up for a free GIMP class with Toronto Library. Want to download GIMP on my MacOS Sierra 10.12.5. What version do I look for? Any other optimum guidance will be much appreciated.

Hi,

Go to gimp.org and look for downloads. You will get the choice of a torrent download or "download Gimp 2.8.22 directly." Choose the latter.

When you try to open it you will get a warning saying it is from an unidentified developer. Go to System Preferences / Security & Privacy and choose the option to "Open anyway."

By the way, you should not post your email address on public forums.

Since upgrading from El Capitan to High Sierra I've experienced many problems with Gimp that all seem related to extensions that use Script-fu. In almost every case script-fu will perform the operations specified then freeze. Only way to get back to using Gimp then is a force-quit of script-fu. But then of course, Gimp must be quit and restarted to regain use fo script-fu for any other process. Everything worked well on El Capitan, but these problems always occur on Sierra and High Sierra. I've tried all the latest versions of Gimp, including the ones that are said to be compatible with High Sierra.... But they're not! This problem with script-fu calls persists in all versions from Gimp 2.8.14 to Gimp 2.8.22 as well as the development version of Gimp 2.9.6.

This is driving me so crazy I'm about to go back to El Capitan! Does anyone know of a fix, a patch or a work-around to stop this behavior? I'm using Gimp on a mid-2010 MacBook 2.4gHz Core 2 Duo with 16 gb RAM and a 1TB hard drive. No problems with any other software, and Gimp worked perfectly until upgrading from El Capitan to High Sierra.

Thanks very much for any solutions!

Hi,

Just to share problems without any solution :-(

After High Sierra upgrade from Sierra on iMac 2017/10:

- Some problem with Gimp 2.8.14: script-fu perform the operations specified then freeze,

- Some problem with Photoshop CS5 : error popup when quit,

- Some problem with Audacity (last current version) : error popup when quit,

- Office 2011 not compliant,

...

- Some problem with internal speakers...

It's a pity...

Eeeek!!!! Audacity, too??? ****! I've not used Audacity since switching to High Sierra, but I will be using it heavily again soon.

This past week I wiped the drive, reloaded El Capitan and then tried transferring files from my Time Machine backup. But... since that was made with High Sierra, it would not restore! Transferring 700 GB manually was too daunting and I was in too big a hurry, so I wiped the drive again, did a clean install of High Sierra and then migrated everything from Time Machine. Took about 8 hours to transfer, so if anyone plans to do this, start it when you go to bed for the night!

I then deleted Gimp and reinstalled Gimp 2.8.18. Surprisingly, Gimp works again with no script-fu crashes. I'm waiting for it to fail, though, so I'm trying to use it a lot this weekend. If it doesn't freeze, I'll stick with things the way they are now. If it does freeze, I'll start from scratch with El Capitan and take all next week to reload my files manually. Ugh!!!

I've also been seeing some strange behavior with Quicksilver, but that's not been consistent, so not sure if it's OS related.

I did set up a second partition on my drive specifically for El Capitan, but switching partitions is a PITA just to use one or two applications. I thought Apple had been around long enough to get it right (especially after the Lion debacle), but apparently not. 😟

Perhaps it "should." But it doesn't. Still freezes on script-fu calls. Script-fu performs the operations, then hangs. Only way to exit is with a Force Quit of script-fu... which requires a re-start of Gimp to use script-fu again. As long as you don't call any operation that requires script-fu, Gimp works. 😟

Is GIMP blocked from installing due to being an unknown developer?

It is, but you if you change the setting to "from anywhere" you should get the option to "open it anyway."

Version 2.8.18 should be OK.

I just installed it using the System Prefs allow from anywhere method. It is working. I had an older version that needed Xcode but the 2.8.18 works by itself on Sierra.

Do it and happy Gimping.😎

Drag into your apps folder and it should work.
