Safe Boot working is a great clue. Safe mode loads only the bare Apple pieces needed to start up, skips third‑party add‑ons, and is meant for isolation. If the Mac runs there but kernel panics on a normal boot (the multilingual restart message), the usual culprits are a flaky peripheral/driver, bad RAM, or a damaged file system. Apple’s overview of Safe Mode is here for context. (support.apple.com)

Try this quick isolation flow:

  • Unplug everything except Apple keyboard/mouse and the display. Then try a normal boot. If it works, add devices back one at a time to find the offender. Apple also suggests temporarily removing non‑Apple upgrades (extra RAM, PCI cards) when chasing repeat restarts. (support.apple.com)
  • Reseat RAM and test with one stick at a time. Panics that happen right after the Apple logo often trace back to memory.

Next, run a file system check from single‑user mode:

  1. Power on and immediately hold Command‑S.
  2. At the prompt, run:
/sbin/fsck -fy
reboot

If fsck reports it fixed issues, run it again until it says the volume appears OK, then reboot. (support.sou.edu)

If it still panics:

  • Try a verbose boot (hold Command‑V) to see where it hangs; the last line before the panic often names a driver. You can also reset PRAM/NVRAM (hold Option‑Command‑P‑R at power‑on) as a low‑risk sanity step. (support.apple.com)
  • On PowerPC‑era Macs, run Apple Hardware Test from the original restore/install disc to rule out hardware. If your model lacks it on disk, some shipped AHT on a separate CD; iDownloadBlog’s guide explains the options. (idownloadblog.com)

Post back with any panic text you see in verbose mode; that will help pinpoint the exact kext or device.
