FAQ
Will this erase my Mac?
Only a clean installation erases the internal drive. Creating the installer always erases the selected USB. Back up before either path.
Can I use a USB smaller than 16 GB?
No. Mojave Patcher requires a USB drive of at least 16 GB; a reliable 16 GB or larger drive is recommended.
Why does text appear every time my Mac starts?
Some Macs cannot natively boot APFS. The patcher's custom APFS boot process can display brief startup text; this is usually normal.
Can I install normal Mojave system updates?
APFS installations can receive updates, but updates may overwrite patches. Keep the USB and reapply post-install patches when needed.
Is Mojave safe for daily use?
Mojave no longer receives current Apple security updates. Avoid sensitive use such as banking unless you understand and accept the risk.
