can't install fresh OS on MacBook Pro 2018 15 inch Touch Bar, I keep getting -2003 and -2005 errors and sometimes -1003

Hello community,.hope someone has some ideas??


I want to download high Sierra and Mojave I'm not sure which was the original OS for the other Mac,.so going to make 2x USB bootable installers just in case, .and try both.


Anyway the issue is I have another Mac that I erased to reinstall a new OS X however the battery died I mean its dead,. needs replacing,. so the clock apparently reset to default so it won't connect to my modem, so I need to create a bootable USB to see if this will work, but it won't allow me to download any other operating system older than the one in my 2019 Mac Pr that I'm using to download the older OS to. .


The dead Mac is a 2018 Mac Pro Touch Bar, I keep getting -2003 and -2005 errors and sometimes -1003 please advise are there any other ways to get this to work,. Ive reset everything that needs to be reset but it won't load from an external drive with operating system either,. or go on the internet even though it appears to sign in ok, but still brings up no internet error. so has to be this clock issue ?? I've tried everything,. please advise thank you in advance.

In Internet Recovery, these low negative thousands error messages indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used (for this purpose) in its current state.


Common problems include:

Hidden Network-name

required use of a proxy server to get Internet access

required use of a login page to get Internet access

Use of a login server or certificate to get Internet access

Use of PPPoE in the Mac to get Internet access (typically only applies to DSL)

Use of Fixed IP address rather than good old DHCP

Variance of the time by more than five minutes

Failure of Router to provide workable DNS server addresses, or providing 0.0.0.0 [may produce -2002f]


If you have an Ethernet port, you may in some cases be able to move your Mac close to the Router and connect to the Router using Ethernet.


The higher the number, the more obscure the problem.


If your battery was completely depleted, the Date&Time could have reverted to the default, which will not work. There is a terminal command to reset to current Internet Date&Time -- post back for assistance.
