Summary

Risk: High — unofficial macOS installer DMGs hosted on Google Drive are frequently altered, repacked, or infected; they bypass Apple’s integrity checks.
Legitimacy: Unclear — Apple distributes macOS via the App Store or Apple-signed installers; Google Drive links offer no automatic authenticity proof.
Usability: Possibly workable but unreliable — some repackaged DMGs boot and install, others fail, lack system updates, or break features (e.g., notarization, Gatekeeper).
Recommendation: Avoid. Use Apple’s official update channels (App Store, Apple Support downloads, or Apple Configurator/Recovery) or obtain installers using official methods.

Key points to check if you still consider a Google Drive DMG

Source credibility — only proceed if the uploader is a known, trusted entity with verifiable reputation.
File hash — request SHA256/SHA1 and verify against an official hash (Apple rarely publishes hashes for DMGs; mismatch is a red flag).
Code signing — inspect the installer’s code signature after download (unsigned or altered installers are dangerous).
Virus scan — scan with up-to-date AV/ML engines (won’t guarantee safety).
Network isolation — install on a test machine or VM first; disconnect from sensitive networks during initial boot.
Backup first — full Time Machine backup and a bootable recovery drive before attempting installation.
Legal/licensing — redistributing Apple OS images may violate Apple’s terms.

Technical issues you may encounter

Gatekeeper and notarization failures.
Kernel extension or driver mismatches causing kernel panics.
SIP (System Integrity Protection) or secure-boot conflicts.
Lack of future updates/combination with Catalina’s 32-bit app deprecation.

Safer alternatives

Download via Apple’s official macOS recovery, App Store, or Apple Support pages.
Create installers using official createinstallmedia tool from a genuine macOS app downloaded from Apple.
Use Apple Configurator or Internet Recovery for older Macs.

Short verdict Do not trust macOS Catalina 10.15.7 DMG files from random Google Drive links; use official Apple sources or validated community releases with verifiable signatures and hashes.
