This image is ready to be restored to a USB drive for installation. Title: [DOWNLOAD] macOS Catalina 10
✅ Pros:
- Ready-to-use EFI folders included for common chipsets (Intel, some AMD).
- No need for a real Mac to create the installer.
- Pre-patched for USB and basic kexts – saves time for beginners.
- Still downloadable from their Archive.org mirror when official Apple links are gone.
On macOS (Using dd command):
- Insert USB and find its disk number:
diskutil list
- Unmount it:
diskutil unmountDisk /dev/disk2 (replace disk2 with your USB)
- Write the image:
sudo dd if=/path/to/Olarila_Catalina.raw of=/dev/rdisk2 bs=1m
(Using rdisk is much faster).
❌ Cons:
- Not a clean, untouched macOS – modifications could cause unexpected bugs.
- No official support – community help is hit-or-miss.
- Risk of bundled extras – some users report unwanted tools or outdated kexts.
- Outdated – Catalina reached end-of-life in 2022 (no security updates).
- Some antivirus flags the image’s bootloader as a hacktool (false positive possible, but risky).
