## macOS couldn't connect to Apple servers on High Sierra

In High Sierra recovery, open Terminal. Run either

* ```nvram IASUCatalogURL="http://swscan.apple.com/content/catalogs/others/index-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog"```
or
* run the installer at least once, quit, open Terminal, then ```nvram IASUCatalogURL="http://$(grep -oE "swscan.*?sucatalog /var/log/install.log | head -n 1)"```

Run `nvram -d IASUCatalogURL` after install is complete (or before using another installer app) to revert the changes.

::: details An easier way
You can use CorpNewt's tool called [HSURL](https://github.com/corpnewt/HSURL) as a shorter way if you don't want to type in the nvram command every time you want to reinstall High Sierra
