How do I delete high sierra?

Having multiple issues with my lap top since installing.

Restore the backup you made before installing High Sierra.

Apple provides this document but it was written for Sierra

macOS Sierra: Revert to a previous macOS version

unless you have another drive or another partition you would need to reformat your drive or install an earlier OS on your current drive. In the event of Sierra you would need an archived installer as Apple has removed it from purchase history on the App Store though it may still be available through recovery.

if you have not done so already it is highly suggested you make a backup and migrate your data back.

Outside of 3rd party support the requirements of High Sierra 10.13 are the same as Sierra 10.12

you may post an Etrecheck report for analysis of your system.
