Slow startup on MacOS Tahoe -- Electron version issue? (non-DB version)

Feedback Bug Reports
1

After upgrading to MacOS 26/Tahoe, Logseq (non-DB version) takes really long to start up. From what I’ve read, this may have to do with GPU-related changes in Tahoe that create problems for older versions of Electron, although apparently newer versions of Electron have solved the issue. Anyone else seeing this? Could Logseq (non-DB) update to a newer version of Electron?

EDIT: Specifically, it takes 25 seconds to launch Logseq on my M4 Macbook Pro. Before Tahoe, there was no noticeable delay.

Hi Lucas,
I use a MacBook Air/M4 with macOS 26.
Logseq starts up within a second or two for me and I haven’t had any problems so far.

It’s a bug of MacOS 26 which leads to performance issues in all Electron-based apps.

You can try the following methods to temporarily solve the problem↓

  • Open a terminal on MacOS26
  • Run the commend launchctl setenv CHROME_HEADLESS 1
  • Restart the app
  • Note this need to be re-run every time you reboots.

Thanks very much to both of you. This is helpful information. I’m hopeful that the tweaks mentioned on the Reddit post that @Eddie_Shen linked to will help with the overall issues I’ve been having with Tahoe. However, even after those tweaks, Logseq is still taking much longer to launch. Perhaps there’s an issue with my specific configuration in the context of Tahoe. I tried turning on logging (via Console) during launch, and several errors were recorded, but I haven’t yet identified exactly what is happening. Anyway, Logseq seems to be running fine once it launches.

UPDATE: So I’m happy to report that my system seems to be running much cooler with these tweaks. However, the slow startup for Logseq is unchaged. I tried timing it. On my M4 Macbook pro with 64gb ram, it takes 25 seconds (!) for Logseq to load. Before Tahoe, there was no significant delay.
