Strange green tinge or yellow tinge to the menu bar

[alexGS]

Hello all,
I’ve searched far and wide but not found anyone with what I’m seeing, nor have I ever seen it on other Macs before… This particular Macintosh (that I was using to test a monitor) has a green-tinged menu bar, as you can see in the photo. I suppose you could say it’s yellow.

I tried adjusting the just-repaired 12” RGB monitor to move the display down (wondering if the phosphors at the top were worn-out). Then I realised that the two icons (at the right end of the menu bar) have correct colours.

The rest of the display has correct colours, especially the white areas, so it’s not a case of adjusting the green gain/cutoff of the monitor. I also doubt it’s a degaussing problem, as it is exactly the menu bar that’s affected. I think I saw the same on an LCD connected to the same machine but will of course test that again when I am able.

Any ideas on a software cause, please? I looked through extensions and control panels and found nothing out of the ordinary, but I do note that disk activity is indicated by a flashing dot in the top-left corner, which feels like it may be non-original.

Cheers

Yeah, there’s definitely something software wise causing that. Try rebooting with SHIFT held down so it doesn’t load any extensions and see what you get.

And yeah there are multiple pieces if software that can add that flashing disk activity indicator.

Yes - or I believe it can also be done as a hack of the system file: booting with extensions off may not fix it. You may have to try with another boot disc.

Thanks for the suggestions - I tried booting without extensions, didn’t change it. It can stay the way it is, there’s a IIci and a IIcx next on the fix-it list (for the same owner) and we’ll just consider it a quirk of that Quadra that doesn’t need fixing

If extensions off didn’t fix it, then I suspect cheesestraws is correct and someone has been playing with the System file in ResEdit.

Kid with Resedit and lots of time; came across same recently in an LCII loaded to the hilt with crap extensions and control panels. Needed a full OS reinstall.

We used to go around to "A Kid" who had a Mac Plus and games. We had to wait outside while he made some duplicates, one day he took ages. "That Kid" spent a solid hour and a half going into ResEdit and editing every dialogue he could find with profanity. Found out of course once we got home.
