Any breaking changes from Sequoia to Tahoe when using web dev tools / apps ?

[anjanesh]

I am on a MacBook Air M2 (24GB RAM + 2TB SSD) with macOS Sequoia 15.7.2.
I am wondering if I should take the risk in upgrading to macOS Tahoe 26.1 ?

I work on web development projects having 2-4 browsers open at the same time with multiple tabs open (~25 in Chrome and in Edge).
PhpStorm, PyCharm, WebStorm, VSCode, SublimeText, Cursor are all open and not closed for weeks.
Terminal is open constantly with 10 tabs and use Termius for remote connections.
I occasionally use Affinity Photo 2 for image conversion if imagemagick doesn't suffice.
Other open all the time are Finder, WhatsApp Desktop, Discord, Slack App, Cleanshot X, GitHub Desktop.
Apache, MySQL, Postgres and some other small services possibly which were installed with brew.
Herd (app for Laravel) are running in the background too.

Install Tahoe on a different partition and test it there until you're confident that your workflow works as expected.

@zevrix's solution is what I've done for several versions now (small nitpick, it's not a different "partition" it's a different "Volume".)

This article covers the steps.

If all goes well, simply delete the old volume & you're off to the races. If you need to roll back, delete the new volume. Couldn't be simpler.

Indeed you're right! I'm still using the pre-High Sierra terminology without giving it a second thought. I guess during my years of using Mac I created way more "partitions" than "volumes".
