You're sitting there, staring at a progress bar that isn't moving. Your Mac is in Recovery Mode because something went sideways, and now you’ve hit a wall. A window pops up with that incredibly frustrating message: the recovery server could not be contacted. It feels like your computer is gaslighting you. You have internet, right? You’re staring at the router. It’s blinking. Everything should be fine. But macOS refuses to believe the server exists.
Honestly, this isn't just a "you" problem. It's a classic handshake issue between your local hardware and Apple’s verification servers. When you try to reinstall macOS, the installer needs to "call home" to verify the software chunks it's about to download. If that call fails, the whole process dies. It’s basically a digital "no dial tone" situation.
Why your Mac is giving you the cold shoulder
Most people assume their Wi-Fi is broken. Sometimes it is, but usually, it’s something nerdier. It’s often a desync between your Mac’s internal clock and the actual time in the real world. If your Mac thinks it’s 2015, and the Apple server sees a security certificate from 2026, it’s going to hang up the phone immediately. Security certificates have expiration dates, and a time mismatch is the number one reason for a failed connection.
Another culprit? Your network's DNS. If you're using a weird ISP-provided DNS, your Mac might be struggling to resolve the specific address of the Apple recovery servers. Think of it like a GPS that can't find a specific house because the map is outdated.
The first thing you have to check: The Clock
Seriously. Don't skip this. If your system time is off by even a few minutes, the SSL handshake fails. Since you’re in Recovery Mode, you can’t just click the clock in the top right. You have to get your hands a little dirty in the Terminal.
Go to the top menu bar. Click Utilities, then select Terminal.
Type date and hit Enter.
If the date that pops up looks like it's from three years ago, or even just the wrong day, you’ve found your ghost. You need to set the time manually using a specific string of numbers. The format is date [month][day][hour][minute][year].
So, if it’s January 16, 12:20 PM, 2026, you’d type:date 0116122026
Hit Enter. Close the Terminal. Try the installation again. Nine times out of ten, this is the magic fix. It’s simple, but it’s the bridge that lets your Mac talk to the world again.
Dealing with the Wi-Fi "Connection" lie
Sometimes your Mac says it’s connected to Wi-Fi, but it’s not actually pulling data. Recovery Mode is notoriously finicky with "captive portal" networks—the kind you find at Starbucks or a hotel where you have to click an "I Agree" button. Those will almost never work for a macOS reinstallation.
You need a "clean" connection. If you can, plug in an Ethernet cable. Yes, I know modern MacBooks don't have the port. Find a dongle. Using a hardwired connection bypasses almost every handshake issue related to Wi-Fi interference or WPA3 security mismatches that older Recovery images can't handle.
If Ethernet isn't an option, try a mobile hotspot from your phone. Cellular data often uses different DNS routing than home Wi-Fi, which can sometimes bypass a local network block that was preventing the recovery server could not be contacted error from clearing.
Erasing the disk: The "Nuclear" option that actually works
If the clock is right and the internet is solid, the problem might be an old, corrupted "Preboot" volume on your SSD. Basically, your Mac is trying to update a system that's too messy to be updated.
You might need to wipe the drive entirely. Not just the "Macintosh HD" volume, but the actual physical disk.
- Open Disk Utility from the Recovery window.
- Go to View > Show All Devices.
- Select the very top item in the list (usually something like "Apple SSD").
- Click Erase.
- Use APFS format and GUID Partition Map.
Warning: This kills all your data. Everything. If you haven't backed up, this is the point of no return. But if you’re already in Recovery trying to reinstall, you're likely past the point of caring about the local files and just want a working computer again.
The NVRAM and PRAM reset
Sometimes your Mac's "brain" just needs a quick slap. Non-Volatile Random Access Memory (NVRAM) stores small settings like volume, screen resolution, and—crucially—startup disk selection. If this data is corrupted, the recovery process can get looped.
If you have an Intel Mac, shut it down. Turn it back on and immediately hold Option + Command + P + R for about 20 seconds. You’ll hear the startup chime twice or see the logo twice.
If you have an Apple Silicon (M1/M2/M3/M4) Mac, you don't do this. Those chips handle these resets automatically during a normal restart. For Apple Silicon, just shut it down completely, wait 30 seconds, and hold the power button until you see "Loading startup options" to get back into a fresh Recovery session.
When the server actually is down
It’s rare, but Apple isn't perfect. Their servers go down. Before you spend four hours screaming at your router, check the Apple System Status page.
Look for "macOS Software Update" or "iCloud Account & Sign In." If there's a yellow or red dot next to them, the problem isn't your Mac. It’s a server in Cupertino. In that case, the only "fix" is a cup of coffee and a few hours of waiting.
Creating a Bootable Installer
If you've tried everything—the clock, the DNS, the Ethernet, the disk wipe—and you're still seeing the recovery server could not be contacted, it's time to stop relying on Apple's servers during the boot process. You need a bootable USB drive.
This requires another working Mac. You download the macOS installer from the App Store, use a 16GB or larger thumb drive, and use the createinstallmedia command in Terminal. By doing this, you're bringing the "server" with you on a stick. Your Mac doesn't need to contact anyone because all the files it needs are plugged directly into the side of the machine.
This is the professional's way. If you work in IT, you always have one of these in your pocket. It turns a stressful two-hour battle with Wi-Fi into a 20-minute breeze.

Actionable Steps to Take Right Now
Stop clicking "Try Again" over and over. It won't work. Instead, follow this specific order of operations:
- Check the Clock: Open Terminal, type
date, and ensure it matches the current second. Manually set it if it’s wrong. - Switch Networks: If you're on Wi-Fi, try a phone hotspot or an Ethernet cable. Avoid public Wi-Fi at all costs.
- Reset the NVRAM: (Intel users only) Force the system to clear its temporary settings cache.
- Verify Apple's Status: Make sure the problem isn't a global outage on Apple’s end.
- Go Offline: If all else fails, find a friend with a Mac and build a bootable USB installer to bypass the recovery server entirely.
Most of the time, that Terminal date command is the hero of the story. Fix the time, and you'll likely find that the "unreachable" server was actually waiting for you all along.
