Question : I just downloaded the new macOS 11 Big_Sur on my Mac mini (2018) and started installing. But even though it said that installing would take about 28 minutes, it’s now about 40 minutes and the installer hangs, the screen is black with just the white Apple-logo and an installer bar that hangs at about 95%.
What can I do ?
Just wait for about 15 to 20 minutes more, and it might just finish the last 5% of the installing process. If it doesn’t, press the power button on your Mac mini until it shuts down completely. Then, restart your Mac mini by pressing the power button again.
Note : this will probably work for any Mac, but it has been tested only on Mac mini (2018).
I would like to get all Macs in my network on macOS 10.15 Catalina. I have some older models (like a MacBook Pro 13″ Late 2011, a white MacBook 13″ Late 2008 and a Mac mini Mid 2007) that are officially unsupported.
Is there any option to get macOS 10.15 Catalina running on unsupported Macs ?
Yes, there is.
It is possible to install macOS 10.15 Catalina on various officially unsupported Macs using the Catalina Patcher by dosdude1.com :
do not do this on your primary Mac !! as this is unsupported by Apple, do not do this on any Mac that is vital to you for your work or study !! using this software is not entirely hassle-free, only do this on Macs that are your secondary computer !!
have a 16GB USB-stick that you can reformat for this
have a stable internet connection (preferably an Ethernet-cable network connection to an internet modem with a high-speed internet connection)
Since I upgraded to macOS 10.15 Catalina, I had to buy the new version of my beloved EyeTV app. So after buying the all new EyeTV 4 (64bit) at Geniatech (who took over EyeTV from Elgato) I installed the app, but whenever I try to run it, I get an “Application not responding” error. I have tried reinstalling the app, but that doesn’t help. I’ve also tried to download and install a newer version, but that doesn’t help either. Deleting the preferences (using the EyeTVreporter.app) doesn’t help either. Even uninstalling EyeTV and all associated files completely (using the EyeTVreporter.app) and then reinstalling doesn’t fix this either…
This is so strange, because EyeTV 4 Beta was running fine on this same Mac…
What can I do ?
The problem is not in EyeTV, it’s in the new extremely strict security and privacy settings that are new to macOS 10.15 Catalina.
To fix this, do this :
quit the EyeTV app by clicking on it’s icon in the Dock while pressing the ALT-key on your keyboard
in the popup menu, the regular ‘Quit’ option will now turn into ‘Force Quit’
click on ‘Force Quit’ and make sure EyeTV app is quit (so there is no longer a black dot below it’s icon in the Dock)
click on the Apple-icon in the top menu bar of your screen
from the pulldown menu select System Preferences
make sure you are in the System Preferences window (main window), if not, click the ‘dots in a grid’-button in the top menu bar of the window
in the System Preferences window, click on Security & Privacy (iron Home icon with circular dial on it)
in the Security & Privacy window, click on the ‘Privacy’ tab
in list on the left, click on ‘Files and Folders’
in the list that now appears on the right, scroll down to EyeTV and put a checkmark at ‘Documents Folder’
if you get a popup warning “EyeTV will not have access to files in your documents folder until it is quit” click the “Quit Now”-button
I would like to know which version of Java I have installed on my Mac, since the software I want to use will only run on Java 7 or higher.
How can I check (and update) ?
Java is a free software platform which is operation system independent (so Mac & PC) created and maintained by Oracle. Despite it always having been a very reliable way of making cross platform games & applications, Apple has restricted the use of Java to ‘only when needed’ by default in the latest versions of OSX and macOS, because of the security risks involved in using Java and similar software that can run autonomously on your Mac next to macOS.
To find out which version of Java you have installed, do the online check that’s on this official website :
Just follow the instructions given and the result of the check will be shown : you will either have the latest version installed, or you won’t… in that case update instructions will guide you to getting the latest version available for your Mac.
Since the latest version of OSX (entitled “macOS Sierra) has been yesterday, I wanted to install it on my Mac. I clicked on “download” in the Mac AppStore and the download started ; on the dedicated product page I could see the status bar filling up and finally stating “downloaded”… but then, nothing happened…
The download wouldn’t install…
I re-checked if macOS Sierra does support my Mac, it does. So I tried restarting the AppStore-app, I tried logging out my iCloud/AppStore-account & than logging back in, I tried rebooting my Mac, I tried rebooting in SafeMode, I tried FirstAid in the Disk Utility app, I tried clicking 10 times on the “downloaded” button repeatedly, I tried installing the DeBug-menus & cleaning the AppStore cache, I tried deleting the hidden AppStore downloads folder… and I tried various command line solutions found online in the Terminal app… nothing helped… I am still stuck with the button under the macOS Sierra icon saying “downloaded”… and nothing happens…
What can I do ?
You are probably not (really) going to like this answer, because this will set you back hours & hours, in which you can’t use your Mac ; but it’s the only way known to solve this, and you need to have a recent TimeMachine backup (or alike) for it :
shut down your Mac
disconnect all cables from your Mac (except your keyboard & mouse if you haven’t got a MacBook)
restart your Mac, and be quick to press the [CMD]+[R] key-combo during startup (your Mac will now start up in Recovery Mode)
in the “OS X Utilities” window that appears, select Restore From TimeMachine Backup and click Continue
in the next “Restore Your System” window, click Continue
now first make sure that your Mac can connect to your TimeMachine-harddisk by plugging in it’s USB-cable, plugging in your Ethernet-network-cable or connect to your WiFi router
then select the hard drive that has your TimeMachine backups on it and click Continue
in the next window, make sure you select the most recent backup that is from before you tried to download macOS Sierra ; only if you’re sure you’ve selected the right backup, proceed and click Continue
now wait (or do something more useful in the mean time) and wait and wait ; this is going to take hours and hours ; putting back a TimeMachine backup this way will go a a speed of about 30BG per hour, so if your hard drive is 500GB it may take you about 15 hours (yes, an entire night and an entire morning…)
finally, once the TimeMachine backup-reinstall is done, your Mac will restart… just let it
then, when logged in, open the Mac AppStore-app and notice that the button under the macOS Sierra now says “download” ; click on it
after the download has completed, you should now see the installer window popup on your screen… proceed from there…
