The real issue is FDA was designed for GUI apps and they never properly thought through how it applies to background processes.
Launchd with a properly configured plist is slightly less painful than cron for this reason, but you still hit walls depending on what you’re trying to access…
Mostly cron jobs and lifecycle rules in my experience, it’s rarely clean. S3 lifecycle policies handle the easy stuff but anything touching multiple systems usually ends up as a scheduled job that someone wrote once and nobody fully trusts.
Have you tried posting in the eGPU.io forums or r/hardware? EU repair shops for GPUs are rare but those communities tend to have up to date recommendations. Also worth checking if any local PC builders in your area do board level repair, they sometimes take on GPU work quietly even if they don’t advertise it.
