MacBook Pro fails to install macOS after reset.

The error code -2005F (which appears as a globe icon with a triangle/caution symbol) on your MacBook Pro 2019 Intel indicates a failure to connect to Apple's internet recovery servers. This is different from a hardware failure - it's typically caused by one of the following:

1. Network issue during recovery:

- Internet Recovery requires a stable Wi-Fi connection

- Make sure you're connecting to a 2.4GHz or 5GHz network, NOT a captive portal or enterprise Wi-Fi (hotel/office networks with login pages will block the recovery download)

- Try a different network entirely (e.g., mobile hotspot)

2. Date/Time issue (you mentioned checking this - good):

- In Terminal within Recovery, type: date 0627120026 (replace with today's date in MMDDHHmmYY format)

- This sets the correct date which is essential for SSL certificate validation during downloads

3. Try a different Recovery mode:

- For the 2019 MacBook Pro (Intel), hold Option + Command + R at startup for "most compatible" macOS installer (often an older version that is more reliable)

- Or hold Command + R alone for the version originally shipped with the Mac

- This avoids downloading the latest Sequoia which may have a larger download that's prone to failures

4. Create a USB installer on another Mac:

- Download the macOS Sequoia installer from the App Store on another Mac

- Use a 16GB+ USB drive and run createinstallmedia:

sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/USB

- Boot from the USB by holding Option at startup on your MacBook Pro

- This bypasses internet recovery entirely

5. If all else fails: The -2005F error very rarely indicates a hardware issue with the T2 chip or SSD. If USB install also fails, contact Apple Support or an Apple Authorized Service Provider.

Decided to reset and start from fresh os as it refused to to install latest os.

Erased ssd and renamed to Macintosh HD with afps and quid selected in drop downs.

Tried internet installation for most up to date install suitable and now have globe witj triangle caution symbol and code -2005F under support. apple link.

@v1v3km is correct this "-2005F" error is some sort of network issue....unfortunately Apple doesn't provide any more details as to what type of network issue. It could be a WiFi issue, local network issue, router/modem issue, or an issue with your ISP, or even your local Internet.

Try power cycling the router and waiting at least five minutes for the router to finish booting before trying Internet Recovery Mode again.

You can try connecting your laptop directly to the router using a USB-C to Gigabit Ethernet Adapter for a faster more reliable connection which bypasses difficult to troubleshoot WiFi issues.

You can try taking the laptop to another location which may have a better network....preferably with a different ISP.

Another option is to perform a DFU Firmware Restore which resets the T2 security chip, system firmware, and internal SSD (destroying all data on the internal SSD). If the process completes successfully, then you will need to use Internet Recovery Mode to reinstall macOS (USB installer is not an option until after you get macOS installed & setup on the internal SSD). If you had not already erased the SSD, then you could have tried the DFU Firmware Revive option instead which should not have affected the data on the internal SSD.

Unfortunately the DFU Firmware Revive/Restore process does require access to another Mac currently running macOS 15.7+ Sequoia or macOS 26.x Tahoe (need to use the Apple Configurator v2.19 app if the host Mac is running Sequoia).

Unless the OP previously modified system security settings using the Startup Security Utility, then it will be impossible to do so after the OP erased the internal SSD of a T2 Mac. Which means it will be impossible to change the security option now since there is no way to authenticate with the T2 security chip since there are no more admin users on the erased system.
