Just in case you delete the folder, but you have to rename it, all your stuff will still be there.

Just read the steps, then follow them.

The most ridiculous is that from Opera's help:

• "Opera recommends backing up your files before upgrading, as well."

but you don't have time to do it. xDDDDDD

Thanks but does this action not delete all Favourites and things like that? Just seems ridiculous to have to do this after an automatic update.

On the second post you have the steps on "How to reset the profile".

The only thing I've been able to figure is that it happens after I use Google Meet (Google Hangouts).

The tool is a diagnostic tool, so it doesn't seem to really serve much of a purpose outside of stress-testing your system and sending results to Apple. I was going absolutely insane from the system lag and found a blog mentioning this fix. Maybe the people with problems were deleting spindump completely or messing with file permissions. The fix creates a symbolic link with the "ln" command, so maybe that makes the system think the file hasn't been renamed. I am not really totally sure what the purpose of the "/usr/bin/true" file is (referencing the link below).

The blog page is here:

Since macOS has SIP now, you need to temporarily disable SIP to make the change or just make the change in recovery. Since you have to boot into recovery to disable SIP, you might as well jut do it in recovery. If you are doing it in recovery, you don't need to use the sudo command and you will have to navigate out of the recovery partition and into the system partition. So I did this:

navigate to system partition:
cd /Volumes/Macintosh\ HD/usr/sbin

Check if you are in the right directory and see if spindump is listed:
ls

Rename spindump to spindump.disabled. You can still run the program manually by executing spindump.disabled:
mv spindump spindump.disabled

Create symbolic link:
ln -s /usr/bin/true /usr/sbin/spindump

That should do it. Then you can boot back into macOS. Keep in mind that after updates, you might have to repeat the process, as they will often create a new spindump file. Then you can do:

Delete old spindump:
rm spindump.disabled

Rename new spindump:
mv spindump spindump.disabled

I hope you are able to get your issue fixed one way or another.

Is it really safe to disable it? See this thing: https://www.takecontrolbooks.com/blog/caution-leave-spindump-alone

This might be a completely different issue, but might be worth investigating.

In particular, it can be due to cryptocurrency mining on a site, which is unfortunately a growing problem. If you think it's due to this, Opera's ad-blocking can help with that in some cases. Enable it in Preferences -> "Block Ads".

Nothing else clear in other entries, then, the clean profile.

You made +/- the same but if you did not made any profile back up, then, once fixed, you have to repeat all the config steps "manually".

At the other hand,
I don't think that opening some tabs, any Opera process should take 100% CPU.

Did you made any recent system change?

Sorry - your tips was not clear for me.

I did something different. I completely uninstalled Opera (using clean my mac app) and reinstalled it again. Fresh opera install, no extensions, no themes. Results are similar.

Is it normal when I open 7-8 tabs one after each other cpu usage (opera helper process to be exact) goes above 100%?

At the other hand,
You can try to create a new profile:

* Use OSync.
* Install "V7 Extensions Manager" - and export the extensions list, if any -.
* Go to Opera://Flags > "Enable import/export passwords" - if any and prefers do not sync them - and export them from Opera Settings > Passwords.
* Go to OHelp > Find solutions - check out the profile folder path -.

--

* Enable "Show hidden files" - choose your prefered option 1-  | 2- | 3- | 4- -
* Go to the profile path.
* Create a profile folder back up.
* Rename the profile folder.

--

* Launch Opera - It will start as a fresh install -.
* Test for a while.

--

If fixed:

* Configure the new profile - Sync, settings, import passwords, Addons… -.

* Once ready, create a back up of the new and working profile.

--

* You can test any workaround to try to fix the older/broken profile - if you want - or delete it.

--

X- Eventually,
you can copy some older profile files to the new profile, but keep in mind that some files may repeat the same problem - or create others -, so before playing testing, create and safe the back up of the fixed profile -.

--

By the way,
keep in mind to create periodical profile back ups.
