You can use Dosdude1's Catalina patcher to download the official Catalina installer from Apple's servers. Disclaimer: I'm not a fan of bodging macOS to work on unsupported platforms, especially for "production" machines. However, if you're looking to tinker and this is something to experiment with to learn, I say have at it. If you need the ...

Unfortunately, this appears to be an issue with HP printer drivers and/or Catalina 10.15.7 - I'm one of many people with the same issue. Lots of us are reporting the same symptoms on the HP Support forums, but at the time of writing there's no fix. Based on experiences so far, HP are ignoring the issue, hanging up on phone calls, or claiming that you'll need ...

Recreating the Problem Before I provide an answer which explains how to install rEFInd to work properly on a Mac with a T2 chip, I will first incorrectly install rEFInd by following a path similar to the one taken by the OP. I do this because the OP posted a comment stating the following. Unfortunately, I had No Security set way before I installed rEFInd so ...

Download new driver from hp support website can solve this problem. eg: https://support.hp.com/cn-zh/drivers/selfservice/closure/hp-laserjet-pro-p1106-p1108-printer-series/5099191?ssfFlag=true&sku=

The HP certificates were revoked due to security breaches and it is not clear if Mac software is vulnerable or just that HP chose to revoke certificates used in both the vulnerable software and Mac software that was not compromised by these specific vulnerabilities. https://www.bleepingcomputer.com/news/security/hp-device-manager-backdoor-lets-attackers-...

However, is it worth actually upgrading? A newer macOS release always includes the latest security patches for any discovered hardware of software vulnerabilities. So generally speaking, it's a good idea to upgrade if your device supports running it, given you have no reason to refrain from upgrading. I know I can't use certain features (such as the ...

Rsync has internal buffers to hold the names of files. These are hardcoded to have a value MAXPATHLEN which is defined to be an OS dependant value or 1024 in the code from https://github.com/WayneD/rsync/blob/d2a97a7ab492e0d0548708251309e077e6aa8c8b/rsync.h So you path names are too long for either macos or rsync

I had a similar problem. I have an iMac running Catalina 10.15.7 but I think my solution will work for any recent OSX version. Basically, I had an unwanted user folder inside my Users folder but this user didn't appear in the System Preferences > Users & Groups menu and so, it appeared that I couldn't delete it from there. If that's the problem you ...

I think the crux is searching for a folder vs searching for a file. Search in open and save works as well as Finder for me - just a different interface and limited space, less affordances are present, but as a long time user of search, perhaps I just have gotten used to the limitations and don’t even see clearly how it’s failing you. When I need more space ...

After realizing the problem only happened in Chrome I disabled extensions and the accent option worked again. The extension responsible is Honorlock if someone else runs with the same problem. Thank you all

The command should likely be adjusted like this: parallel -j32 cp -rpf {} /Users/henry/ ::: /Volumes/henry/* Note the asterisk, this will allow parallel to parallelize across the folders/files present to be copied within the top level of /Volumes/henry/. With the above command, there will be as many concurrent copies as /Volumes/henry/* expands to, which is ...

XPC Services From Apple's Creating XPC Services: There are two main reasons to use XPC services: privilege separation and stability. Stability: Let’s face it; applications sometimes crash. We don’t want it to happen, but it does anyway. Often, certain parts of an application are more prone to crashes than others. For example, the stability of any ...

Sidebar text size cannot be adjusted independently. However, this setting: System Preferences > General > Sidebar Icon Size changes the size of the Sidebar icons and text names.

I'd recommend a couple of things: Make sure cron has Full Disk Access in the Privacy tab of System Preferences (see s/s below) When creating commands in crontab, help yourself out by writing errors generated by stderr to an output file using 2>&1, and using full pathnames (your cron job does not run w/ same environment as your user does); EXAMPLE: ...

No, Catalina has not broken the logging into external machines in general. The problem must be local to your machine or your network. I regularly use the commands you mention (ssh and mysql) to connect to external machines from a Mac running Catalina - so in general it works just fine. I would start by ensuring that you have: a) a working internet connection ...

That is how Calendar indicates that you have responded with a 'Maybe' to the meeting invite. There isn't a way that you can create your own meeting and respond to yourself with a maybe. However, you could create a separate calendar account and send yourself (original calendar) invites, to which you respond 'Maybe'.

One primary purpose of the "nextonly" option is to allow for installation of a startup manager. For example, if you install rEFInd as a boot manager, then you would configure the Mac to always boot to rEFInd. This boot manager can be configured to display different operating system to boot. After a selection is made, rEFInd instructs the firmware ...

Something which might help (but it doesn't go all the way) is to enable the 'Reduce motion' option in the System Preferences section Accessibility:

This is what solved the issue for me. You will need another Apple computer running Catalina. Make time machine backup of the working computer. Boot in recovery mode in the non-working computer. Recover from that backup. Continue from there... Hope this helps, and that you have access to another mac with catalina (in that awful village where you live ...

I am having the exact same problem. Something weird that helped me past the "downloading instaler information...failed" is using different wireless connections, and retrying many times. Some (magical) times it just passes to the next screen. This is very weird, I know, but it helped in my case. When I get passed that error, I find a different one: ...

There's no "translucent box" in Catalina, that was for previous versions of macOS. To do that, you would click and hold the green button. Catalina uses the "hover" method. Hover over the green button and you'll get a popup allowing you to select "Full Screen," "Tile Left," and "Tile Right." Personally, I've ...

According to Apple: "[...] you cannot define keyboard shortcuts for general purpose tasks such as opening an app or switching between apps." https://support.apple.com/guide/mac-help/use-global-keyboard-shortcuts-mchlp2262/mac But maybe you can share your specific needs so we may find a solution.

There is an app named Note2Txt which will convert all your notes to a text file. One file for each note. it runs very fast and you can store the text files wherever you like. It works fine normally but i had a problem with it on Catalina. There is also an app named Exporter which will convert all your notes to Markup files. Again you can put the output to ...

I fixed this by doing the following: I ran diskutil list. Then from that list, I checked which part of my disk was the one apple was using in the GUI in my original question by checking which one's size was also 42.74 GB (Its identifier was disk0s2 in my case). I ran sudo diskutil apfs resizeContainer [the identifier we retrieved above] [the size we want ...

Most issues with web browsers in general, including Safari, can be traced back to just a few things: Damaged/Corrupt cache Damaged/corrupt settings file(s) Damaged/misbehaving add-on/extension The first thing I would do is close all your tabs then go to the "Safari" menu and select "Clear history..." Change the pop-up menu to clear &...

I just had a Macbook Air with Safari that would immediately crash when trying to launch. This was on a Mojave system. To fix, I would up reinstalling OS (reboot and press and hold Command+R). Safari is now working fine.

I found a solution for the problem, meanwhile. Here's what worked for me: In the "System-Preferences" it was demanded to update the Apple-ID. After doing so, I shutdown the machine. Then started it again. The problem is now gone. The accountsd-process is still there in the processes-table, but the use of system-capacity is back to normal.

As of Sep 2020, the steps to do this on High Sierra or Mojave are: Make sure you have Security Update 2020-005 installed Enrol your device in Mobile Device Management. For those that have a workplace or school that already use MDM, this is simple - just follow their instructions for 'bring your own device' setup. For those that don't, you can setup your own ...

The answer to your question is given in Mac OS X Process Memory Statistics by Mike Ash: RSIZE: The total amount of physical RAM used by this process.
