Thanks for your response, Jeff.
Here is a more detailed and complete list of different things I've tried to remedy this.
1. Check global Adobe CC plugins path/Follow entire Alien Skin recommended uninstall workflow (Hard Drive/Library/Application Support/Adobe/Plug-Ins/CC)
***Did not resolve issue, this path does not exist Hard Drive/Library/Application Support/Adobe/Plug-Ins/CC. The "old" Photoshop plug-in path did not exist or was deleted at the time I checked due to uninstall of Photoshop CC.
2. Start Photoshop while holding down Shift key to skip loading optional and third-party plug-ins to determine if the plug-in no longer appears.
***Did not resolve issue, was able to select this option at application startup but the menu item still appears.
3. Use Creative Cloud Cleaner Tool
***Did not resolve issue. I used the Creative Cloud Cleaner tool to remove Photoshop and upon re-install, the menu option remained.
4. Delete Photoshop Settings File (Command + Option + Shift (Mac OSX)
***Did not resolve issue, was able to select this option but the menu item still appears.
5. Try installing and un-installing older versions of Alien Skin products
***Did not resolve issue, only created a separate set of installation files which I was able to remove. The installers did not seem to come with an uninstaller for Mac.
6. Manual reset of Photoshop preferences by deleting PluginCache.psp and Adobe Photoshop Prefs.psp both in Macintosh HD/Users/[Username]/Library/Preferences/Adobe Photoshop CSx Settings/
***Did not resolve issue, was able to locate and delete both files via Finder, but issue was not resolved upon application restart.
Feeling a bit hopeless here. Clearly, there is a file somewhere which is causing Photoshop to load these menu items. I'd really appreciate any help to get this resolved.
Wow! You really deserve a gold medal for all the things you've tried! (I mean that as a compliment!)
This may sound simplistic, but when you said that you were able to locate the files via the Finder--does that mean you physically opened the plug ins folder and pulled them out of the folder? Did you trash them and throw away the trash and then restart your computer and then restart Photoshop?
If the answer is yes, then I don't have a better answer for you. But I just want to encourage you to not give up hope. There are a lot of good people on the forums to help.
Hang in there,
Yes, when I found any of the potentially offending files I selected them in Finder and deleted them. I've since then cleared my Trash and have restarted my Mac.
Thanks for the response! I was pretty sure, but I had to ask. We'll keep working on it until something breaks!
2.5 hours on the phone with Adobe support resulted in determining the location of the plugins, which was atypical for such an installation.
The file path on my MacOS: /Library/Application Support/Adobe/Plug-Ins/Alien Skin/
This entire situation was made frustrating because various searches in Finder and Spotlight did NOT turn up any search results for "Alien Skin", "Snap Art 4", or "Exposure X2". This is despite those exact phrases being in the containing folder.
I will say that I'm clearly not a computer expert, but I did learn that going to "/Library/" in Finder's "Go to folder" menu option will result in showing you MORE folders and files than you'd be able to see just by accessing Library a different way. This "/Adobe/Plug-Ins/" folder was not visible at all when I accessed Library by using the "Alt/Option" method.
I hope this helps someone in the future who may struggle with removing plug-ins from Photoshop.
I would also like to add that I'm disappointed I had to escalate my call to a supervisor to get the issue figured out. The supervisor also tried to blame the plug-in for "staying" in Photoshop. My entire point was that Photoshop MUST know where the plug-in is being pulled from and therefore Adobe should be able to determine where that location is so the offending fie could be removed. I'm glad that it was eventually able to happen. When calling, expect what you deserve and not an ounce less.
Thanks for the help I received.
