Macair certain parts of screen aren't clickable

What the f? The same thing happened at the same exact time as well. Yesterday afternoon, 1/4 of my screen became unclickable on MacOS 10.15 Catalina. I did the security update as well and it is the same exact issue. Apple did something to our computers. I have a MacBook Pro Intel 2019

Here is a potential fix: It is not MacOS, it is the Grammarly Desktop Application. When deleted and reinstalled, the issue goes away completely.

I tried moving the dock around. Moving to the left side still leaves the right side of the screen unclickable. Moving the dock to the right side makes the right side clickable, but now the left side of the screen is unclickable. My question is Apple, are you really going to deliberately malfunction older macs and tell us the problem is the track pad, knowing full well that it is clearly a software issue? How else do you explain so many people having the same exact issue in the same day? I read another thread where support was adamant that it was a track pad issue because the computer was old. They almost refused to acknowledge that the issue happened whether with the track pad or mouse. Come on guys. Do better.

Call Apple Support and ask to speak directly with the Manager or Senior Supervisor. I told them in detail what the issue was and they collected a screen recording and diagnostic data. They told me they will sent this to the MacOS team and give me an update within 1-3 business days.

It does work, thanks!!!! But how exactly does this app interfere with the scope of the trackpad function? Can someone explain?

Another query: I don't recall having installed Grammarly at all. The 'Grammarly Desktop' app seems to have been 'created' on Friday 1 Nov 2024 at 5:45 am' (whilst I was asleep) and 'Modified' on Friday 1 November 2024 at 8:05 am (I assume this was when I turned the laptop on). And indeed, the problems started right when I turned it on.

And I appear to be signed in, and Grammarly appears on my Dock (I did not put it there.) How did all this happen without me doing anything (or without my awareness)?

Someone else is having the same issue with their MacBook Pro: MacBook Pro screen not responsive - Apple Community

I have the same issue. This morning, exactly the following issues were encountered as in the OP. I am having an issue with 1/4 of the right side of my screen, appearing non-functional. I can use my trackpad or wireless mouse over the other 3/4 of the screen but any icons on desktop or even Chrome browser on the 'dead' side of the screen just cannot click.

• When I move desktop items to the left side, the trackpad works on them. when I move them back to the right, they are not clickable.
• When I reduce and shift the open web browser to the left of the laptop screen, trackpad is working fine on all areas of the page. When I expand back to the right, 1/4 of the right hand side of the web page is un-clickable.
• Alerts are not clickable, as they often appear on the top right.
• Opening a word document - functions/tools on the top right are not clickable, but when I reduce size and shift to the left, the same functions became active/clickable.

What is the reason for this? And what can be done to fix it WITHOUT reverting to safe mode? Thank you.

Update, reading some (often 10+ years old!) advice, I played with the dock. When I move it to the right hand side (vertically), then the non-clickable area moves to the left 1/4. Go figure.

Going full screen solves the issue for the web browser, with the 1/4 right becoming clickable. But not for a simple word document, where 1/4 right side is still not clickable.

Please share what they say.

You were 100% right. This is exactly the fix. Thank you so much. Was thinking I would have to buy a new laptop because customer support said it was probably because it was an older computer. Wildy incorrect. TX!
