We all know that it’s important to “stay patched, so you stay secure.” But macOS is making that a bit harder these days. Apple really wants you to upgrade to macOS Big Sur, but if you’re not ready for that big jump, it may be hard to notice that you have macOS Catalina and Safari updates to apply.
Catalina app (also referred to as the macOS installer). What is a silent, in-place upgrade? A silent, in-place upgrade is a method of upgrading a Mac computer to a newer operating system with minimal user interaction with the installer app. By using the “startosinstall” command you can.
macOS Big Sur is a huge change and it’s usually a good idea to let the bleeding edge folks work out the kinks. It’s also not a bad idea to wait for Apple to make at least its first update before jumping on the new hotness. You may have applications that are not yet macOS Big Sur-compatible so be cautious with a big upgrade like this. I’m not a proponent of waiting a long time to upgrade to the latest OS but caution, especially on such a big change, is definitely warranted. While you’re waiting for the OS to stabilize, you want to keep macOS Catalina up to date, but Apple makes it difficult to see just how to do that.
- If you are running OS X Mavericks or later, you can upgrade to macOS Catalina. General Requirements. OS X 10.9 or later; 4GB of memory; 12.5GB of available storage with OS X El Capitan 10.11.5 or later; 18.5GB of storage space when upgrading from OS X Yosemite or earlier; Some features of Catalina may require a compatible Internet service provider.
- Answer (1 of 20):. I’ve already upgraded to Catalina and it works fine for me. There is a very small group of people who ran into a small problem when upgrading to Catalina, this is a much smaller group than usual so this is excellent performance for a major upgrade. There were a small.
While you’re still on macOS Catalina, if you open System Preferences and select Software Update, you’ll see the icon for macOS Big Sur with an obvious “Upgrade Now” button. But we don’t want to upgrade to macOS Big Sur just yet.
When I took the screenshot for this post, I actually had updates to macOS Catalina and Safari waiting for me, but it sure wasn’t obvious they were there.
Under the icon for macOS Big Sur, there was some smaller text that said, “Other updates are available” and blue link text that said “More info…”
Click on that tiny More info link to reveal the updates you really need to apply. In my example, I had macOS Catalina 10.15.7 Supplemental Update waiting, and the notes below clearly say that this update “improves the security of macOS.” There was also a Safari update to 14.0.1 which had some speed enhancements but also security fixes, including the removal of support for Adobe Flash. You really want this update!
After you apply any Safari or macOS Catalina updates, the Software Update Preference Pane will still say “More info…” As shown below:
But if you click the link now, it will take you to the Apple web page telling you about all the awesome features of macOS Big Sur. I presume this “More info…” link will change back to showing you security updates for macOS Catalina and Safari when new ones are available, so you’ll have to be vigilant and pay attention in looking for the updates.
I don’t like that Apple has made it so undiscoverable that security updates are awaiting us. I would really prefer that they had made two equally-obvious buttons, one to upgrade to macOS Big Sur and one to update macOS Catalina and Safari. They’re doing a disservice to the community by making it this hidden. As I said up front, I’m a big proponent of getting on a new OS when it’s practical to do so, but it is the user’s decision when to do it and shouldn’t be tricked into what could be a catastrophic upgrade.
Since you’re probably the family nerd if you’re reading or hearing this, please pass this post along to your friends and family so they stay patched so they stay secure.
There is no macOS Catalina 10.15 available, Apple removes all previous full installers from the App Store
when a revised version is released.
The package you downloaded is not the upgrade installer app but an update for Catalina, you need
to be running a previous version of Catalina before that will install. Put it in the Trash, empty the Trash.
You need to download the full installer app from the link below,
Open Safari and click on the blue text,
Go to Check Compatibility to see if your mac qualifies for macOS Catalina.
If it does go to the Download OS section and click on macOS Catalina 10.15.
This will redirect you to the App Store Catalina download page it should say
Get or Download.
This will download the Install macOS Catalina.app directly to your Applications folder.
It is about 12.24GBs in size so will take a while, be patient.
Double-click on the installer app to install Catalina this will install a full working version
of Catalina and the version will be the latest/ last ver 10.15.7.
Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading
and do not use any other devices that share the same internet connection.
Upgrade Os From Yosemite To Catalina
If the App Store says ‘Open’ then it is detecting a previous download of the install app
go to the Applications folder locate Install macOS Catalina.app.
Move it to the Trash, empty the Trash.
Restart, click on the link again, the App Store should say ‘Get' or 'Download'.
As you are considering upgrading to Catalina be warned it does not support 32bit apps.
Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,
some updates may be free, some may be paid. Use this app to discover which apps you have
