Troubleshoot the Mac's WiFi:
I. Close All Open Apps:
Something may be eating up the system resources, thereby decreasing the WiFi capability. So, start with closing all apps.
II. Restart your Router:
- Power: off the router
- Wait: 30 seconds
- Power: It back on
III. Boot in Safe Mode:
In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install. For instructions, go here: How to Use Safe Mode on your Mac - Apple Support
IV. Reset your SMC and your NVRAM:
(Applies to Intel-Basel Macs Only) Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. Networking) become corrupted, technically. So, reset both on your Mac. So, reset the SMC and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.
Start With This:
V. Use Ethernet:
If you cannot connect to WiFi, then use Ethernet. This is the adapter you would use, connecting the cable from the computer to your router: Belkin USB-C to Gigabit Ethernet Adapter - Apple Support
