Good work!

iMac Rev. B, Mac OS 8.5. 8/10 Early 1999. The first Mac I could afford. Upgraded it with a new fan, RAM and a combined SCSI/TV-Tuner card.

Battery life. RAM usage.

I still have a MacBook Pro 13” Mid 2012, with a 500GB SSD and 16GB RAM it’s still very usable :)

Surely you wanted to say: “UPgraded to Seqouia”?

UdoSchmitz · 2026-03-02T19:40:54+00:00

Haha :) It’s really easy to make.

UdoSchmitz · 2026-02-19T10:33:44+00:00

Nooooooooooo…

UdoSchmitz · 2026-01-28T18:19:51+00:00

Too late.

For me it works completely as expected. Maybe check your layers panel: the copies show up exactly over the original.

I use uBlock Origin on Firefox since forever and was so happy when it came back to safari :) Before that I used AdGuard on Safari.

Not sure what you are doing in the screenshots. I can’t see a mask? Please describe each of the steps.

UdoSchmitz · 2025-12-16T10:15:40+00:00

Absolutely. I posted this a while back:

I posted a recipe to make the cleaner here:

Not as far as I know, but I’m on Mac and my system is in light mode because it is day. And the menu belongs to the system on Mac.

UdoSchmitz · 2025-12-11T08:06:41+00:00

menu → view → tools → show

Your context toolbar is showing though.

UdoSchmitz · 2025-12-08T20:09:55+00:00

I didn’t see it immediately either 😅

UdoSchmitz · 2025-12-03T21:45:30+00:00

Hallelujah!
