macos – Cant update/install homebrew packages with Kaspersky Security Software (Self Signed Cert)

At work we have Kaspersky installed. Kaspersky installs a self signed cert so it can decrypt/inspect web traffic. Chrome and everything works fine except for homebrew. When i try to install/update software this is what i see:

brew install yarn
==> Downloading
######################################################################## 100.0%##O#- #
curl: (35) error:1400443E:SSL routines:CONNECT_CR_SRVR_HELLO:tlsv1 alert inappropriate fallback
Error: Failed to download resource "yarn"
Download failed:

Since it appears its a curl issue i tried to create a .curlrc file with insecure but that doesn’t help at all. I’m able to call one of our IT admins over and temporarily turn off web anti-virus but that is starting to be a major pain every time i install/update software. They aren’t, of course, going to allow me to permantely turn it off. I have this issue on no matter what mac i use (one is a m1 based mac and the other is an intel based mac).

macos – notes sync mojave vs ios14

I remember that I read somewhere that notes in iOS 14 will not be compatible with notes in Mojave. But I cannot find any more updated information. Some claim that they only stop working after one upgrades the format in which they are saved on iCloud.

Can someone please post their experience/knowledge whether it is safe to upgrade to iOS 14 without losing sync of notes with OSx running Mojave.

Finally, can you please list what will break down by such an upgrade (iPhone to iOS 14 and osx left at Mojave).

macos – Google Chrome Download Weird Redirection

When I go to, I get redirected to sign in and then forwarded to some app engine link as can be seen in the continue parameter of the following url:


(Please don’t click the link unless you know what you are doing, as it is potentially suspicious.)

I tried to sign in with a test account to see where it goes, and eventually ends up at the following link:


(Please don’t click the link unless you know what you are doing, as it is potentially suspicious.)

I recommend no one click on the suspicious links, but I am just trying to see if anyone has encountered this issue and / or knows why it happens. (I have removed the hyperlinks so no-one accidentally clicks them.)

I examined it on VirusTotal as well but could not find much more info and it doesn’t trigger any engines:

Clearing my cache on my machine corrects the problem and I am able to get to the correct page when going to However, I tested some time later and it seemed to happen again. Since it is only happening on this machine on my network and not others I am wondering if the cache on it is somehow getting poisoned, and if so how. It is an M1 Mac mini if it is of any relevance.

I also reset the wifi-gateway and password but was able to reproduce it on that same machine after sometime. This was also after I had completely re-formatted the hard drive and had done a complete re-install of the OS from the recovery partition.The problem seems to reoccur again maybe about 30 minutes after clearing the cache. Also if I try to visit the link multiple times quickly, about 50% of the times I will actually end up on the correct Google Chrome download page, and the rest of the times I will be redirected to:


I would really appreciate if anyone can shed any insight, because I am kind of worried why this is happening and if this machine and / or my network is potentially compromised.

How to save and use macOS’ Zoom credentials on Keychain?

I have multiple Zoom accounts and need to switch between them on a constant basis. On iPhone, the credentials are saved on the Keychain, which makes it easier to switch between the login accounts and not needing to type username and password every time. On macOS, I can’t find how to use these credentials from Keychain. The Zoom app doesn’t offer that choice.

Can we change Windows 10 behavior to be MacOS like?

I’m using Windows 10 but am more comfortable as a Mac User and I really miss some behaviors I’ve come to expect. I own a 32” 4K monitor and now with Windows 10, my windows get maximized at full everytime is not ideal.

Have any other fellow users which alternate between Mac and Windows have found a solutions for this item? My research for tools yields results about changing the looks of windows more like mac and that’s not what I’m interested in. I want the rezise/maximize behavior to make me as efficient as in MacOS.

I hope you can point me into the right place to find a solution for this.

Are windows controls on Windows 10 modifiable?

macos – Removing free partition on Macbook Macintosh HD

Let me tell you the story to understand the problem.

I installed Ubuntu 20.04 on my mac as the second OS. Later I decided to delete it, and being not good in all this stuff, I decided to just remove the 30gb partition I gave for Ubuntu. However, EFI partition was left.

I downloaded Paragon and erased this EFI. But it is not merged still with my Macintosh HD!

Paragon - disks structure

So my question is how to merge it (include literally the 314.57 Mb partition) with my hard disk (APFS-container)?

I tried to format it as HFS+ and then tried to make it APSF but my system felt and I had to install macOS again.

P.S. Disk Utility says that there is a trouble and to repair it, I need to go to recovery mode. But when I go to RM, it says the same thing – even though I turned off filevault as some sources say.

I will be very thankful to you for your response!

macos – “Find My Device” equivalent for Linux

I’m thinking of switching to Linux (either Debian or Ubuntu, haven’t decided) from macOS. One of the features of macOS I love is “Find My Device,” which allows me to locate my device if I lose it, remotely play a sound bypassing Do Not Disturb, erase my device remotely (while still preventing other people from using it through “Activation Lock”), and displaying a message to any passerby. Is this possible on Debian or Ubuntu? If so, what package can I use? I’d prefer for it to be self-hosted (am averse to sharing my location with random, unknown companies) and free software (both in price and freedom).

macOS 11: Get system information (GPU, resolution) programmatically (in C)

I need to access data about GPU and screen resolution in C, not using system_profiler, because it takes too long(.3s-.5s system_profiler SPDisplaysDataType), and needs greping and cutting, which is not that fast either.

Caching would be answer, but very short-sighted as someone can use different monitors etc.

Unfortunately system_profiler is closed source.

macos – Two Bootcamp installations: first one on Internal HDD and second one on external Thunderbolt 2 SSD

after following this detailed guide I’ve stuck at point 5. which did not make my external 5TB HDD to boot, no “Install Windows” nor “Windows” shows in boot selection menu:

bless --folder /Volumes/WINSTALL/efi/boot --label "Install Windows"
mkdir /Volumes/WINSTALL/label
bless --folder /Volumes/WINSTALL/label --label "Windows"

Current disk configuration of iMac 2012:

  • 1TB internal HDD (currently installed Catalina, Windows 10)
  • 240GB external SSD (Thunderbolt 2: currently installed Mojave, High Sierra)
  • 5TB external HDD (USB: empty)

Target is to install Windows 10 on external Thunderbold2 240GB SSD along with the other OS installations.

Because the first attempt with external 5TB HDD did not work I tried to use 240GB SSD with Bootcamp Assistant in Mojave (OS booted from that SSD) to create installation USB-stick and to create Bootcamp partition on SSD with ISO Win10 64-bit 1909 as recommended in the guide.

At point 8. I tried to assign letter “S” to EFI partition on SSD but it failed with message There is no volume specified. Please select a volume and try again. So I tried to mount the partition with command mountvol S: /S without success and when I tried to run mountvol with no arguments it did not even show EFI partitions from the other disks as an option.
