If your printer needs a driver to work with your Mac, you need a 64-bit version of the driver for macOS Catalina. Most printer manufacturers already released 64-bit updates to their drivers, so you should check for new updates. Discontinued printers may never get a 64-bit driver, making it very difficult to fix problems with it in macOS Catalina. Jun 16, 2020 Mac Pro introduced in 2013 or later.

New macOS updates always come with problems. The same applies to Catalina.
Although Catalina might seem to have had a great start, issues are now slowly surfacing. And recently, Mac users who had just updated to this new macOS reported having problems with their WiFi. According to them, Catalina caused the WiFi to stop working on their Macs.
WiFi not turning on after updating to Catalina? Can’t access the web after installing Catalina? Is the WiFi icon not showing after the update? Whether it’s true or not that Catalina caused the WiFi issue, we’ve got great news. We have prepared a few handy fixes that can possibly fix your WiFi problem. Check them out below!
Some Mac users said their WiFi had simply stopped working after updating to Catalina. Whenever they attempt to connect, nothing happens.
To fix the issue, try to restart your WiFi network. Click the WiFi icon on your Mac and turn the connection off. Wait for 15 to 20 seconds before reconnecting to it. Do this a couple of times.
If it does not work, try to restart the router itself. Sometimes, it’s the ISP that’s having problems. To restart your router, switch it off, wait for 10 seconds, and turn it back on.
Now, if restarting the connection and the router doesn’t resolve the problem, restart your Mac in Safe mode and check if the WiFi is working.
Here’s how to restart your Mac in Safe mode:
If the WiFi is working fine in Safe mode, it is likely that incompatible extensions and apps are causing the problem. Fix it by installing the app and extension updates that are compatible with Catalina.
To update apps and extensions, follow these steps:
Should you wish to automatically install apps and macOS updates in the future, do steps 1 and 2. And then, choose Automatically keep my Mac up to date. When your Mac detects new updates, it will send you notifications.
Can’t connect to a WiFi network after updating to Catalina? Are you noticing an exclamation mark on the WiFi icon on your Mac? Then it is possible that a network error exists or a hardware component is at fault.
To fix the problem, you might need to renew your DHCP lease address or acquire a new one, which establishes a connection with a new IPv4 address, router, and subnet mask. Here’s how to renew your Mac’s DHCP lease address:
You’ve restarted the router. You’ve also renewed your DHCP lease address. But the problem is still there. What should you do?
Deleting the WiFi profile from the list of networks saved on your Mac usually does the trick. Here’s how you do it:
There are times when you are already connected to a WiFi network, only to find that your browser does not load. Worse, it does not even connect to the server.
If you have successfully connected to a WiFi network but your web browser does not load, the problem might be with the extensions, cache, or cookies. To fix it, simply clear your cache, remove the cookies, and delete any unnecessary web data stored on your Mac.
If the manual process seems too overwhelming to you, opt to automate the process. For this, you will need a reliable third-party Mac repair tool like TweakBit MacRepair. Once you have installed it, run a quick scan to find any junk files, such as browser cache and cookies. It’s that easy!
Assuming you’ve done everything but the WiFi problem persists, your last resort is to seek help from experts. Take your Mac to a nearby Apple Center and have an Apple Genius check the problem.
