This contains the.app installers for Mac OS X 10.9 Mavericks - 10.15 Catalina. Flash the.app file to a USB Stick using the provided copy of Install Disk Creator. Boot to the USB Stick. Set the date back using the setup terminal using the date command. Install as normal. I know that by using VM can help create a macOS bootable USB but my macOS didn't start, so I cannot install VM software on my Mac. Finally, I downloaded and installed UltraDMG software on my another Windows 10 computer and it helped me burn macOS 10.15.6 DMG image file to my USB drive, then connect my USB to my Mac then boot from USB, it starts.
2019 is one of the great years for computer users and smartphones user.

Macos Catalina Usb Creator Windows 10

- Upgraded 2 of my 3 macs on Catalina. No problems. My final machine (iMac) will have to wait as one piece of crucial software (from Hikvision) is still 32-bit and who knows when these clowns will make it 64-bit.
i did an upgrade, then a clean-install to see what bugs have been put in. So far, all solid. - The easiest/best way to do this is to use Install Disk Creator.
Which has not been updated since Dec 2018The easiest/best way to do this is to use Install Disk Creator.
Yes, DiskMaker X is ready for Catalina but it’s in beta at the moment. According to developers Twitter page, it should be ready by the end of this week hopefully.DiskMaker X is now Catalina ready.- Catalina is the buggiest system I ever loaded on a computer. Small but annoying problem; Can't update Apps, can't download Apps, changes Mail.

Nope. It works fine. You can see it works in the attached screenshots.The 'quoted' command is incorrect. Wrong: »sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia—volume /Volumes/USBdrive —/Applications/Install macOS Catalina.app« Correct: »sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/USBdrive --/Applications/Install macOS Catalina.app« The use of em dashes instead of two hyphen-minus characters will result in the command not working, as does the omission of the space between 'createinstallmedia' and the first two hyphen-minus characters.
I appreciate what you're saying and why. - Copied and Pasted...Didn't work. Manually type worked. Strange...
- I encountered a few problems doing a Catalina upgrade:
1) The Catalina post-installation got stuck forever (hot spin), or at least overnight for > 12 hours, at the 'Setting Up Your Mac,' phase on my 2013 MacBook Pro. I DuckDuckGo'd the symptom and found that several other people are having the same exact problem on a variety of Macs. The workaround, which I consider very dangerous, is to do a hard reboot of your Mac. It seemed to work but anytime you interrupt something having to do with installation and setup you run the risk that something isn't configured quite right.
2) The MobileMe AppleID Curse came back once again to haunt me. I'm a former MobileMe subscriber (sad, I know) who also had an AppleID for iTunes purchases. When iCloud came along my MobileMe credentials were converted to iCloud credentials as an AppleID. However, I also had the iTunes AppleID but despite an initial promise from Apple to merge these two IDs, Apple subsequently refused, and still refuses to merge my two Apple IDs. Getting the US nuclear launch codes requires a lower level of authority than what it takes to merge Apple IDs. Not a joke. Anyway, once Catalina started doing its thing to associate my AppleID with various services on my Mac it defaulted to using my ex-MobileMe AppleID - for everything. The problem is that most of my purchases, like thousands of music tracks, apps, books, iTunes in the Cloud, etc., are associated with my ex-iTunes AppleID. Sounds like an easy switch, but nope, I ended up having to reassign everything manually and re-download a boatload of content.
3) I could not enable Keychain. No matter how many times I entered my credentials it still refused to activate. The 'solution' was to log out of my ex-MobileMe AppleID account, which is associated with my iCloud subscriptions like cloud storage and log back in. To do this I had to first manually disconnect from every service shown under AppleID in preferences. This temporarily severed things like Photos, Mail, Contacts, Calendars, Reminders, Safari history, Keychain, Find My Mac, Notes, etc. Once I shut everything down (and I selected the Save option on whether to keep iCloud content on my Mac) I was able to sign back into my ex-MobileMe AppleID and activate Keychain. The OS then asked me, one by one, whether to reconnect each of the services to iCloud, which I did. However, a side effect of this is that Photos now thinks, as it always does if you sign out and sign back into iCloud, that all of my roughly 32,000 photos must be uploaded to iCloud. It's now been churning away for a couple of days even though everything in my iCloud matches what is on my Mac. I think it stupidly uploads the whole photo, then realizes it's already on the server and discards it. Talk about a massive waste of bandwidth. (Sidenote: Amazon Photos does the same thing). It seems to me that they could do something like a checksum or CRC based comparison/handshake, at least as a first pass, before uploading the entire photo.
Anyway, definitely not what I'd called a 'bumpless' upgrade. Not to sound damning, but installation issues always set a bad tone for a product. Apple could have and should have rooted out these problems ahead of time. To them this may sound like a toe stub, but to end users, it is a royal pain in areas far north of their toe. - Copy & Paste of.. 'sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia—volume /Volumes/USBdrive —/Applications/Install macOS Catalina.app' does not work for me. It says Command not found.
Copy & Paste of either of those did not work for me but this did....

We'll look into it again, but as presented, the original absolutely works in two different AI locations.

sudo /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled- I'd suggest the instructions say 'name the USB stick USBDrive' from the get-go. After decades in this business, I have lost count of the times that people miss such a basic instruction as 'Make sure to change the element titled 'USBdrive' for the name of the drive you intend to become the bootable installer. '
We’ve been seeing these kinds of comments for over twenty years with each release of a major upgrade to macOS. Someone always declares something to be the worst, buggiest, most stupid update ever. Point being someone is always going to have problems no matter what. So no, Catalina is not the buggiest system ever loaded onto a computer and someone will be along shortly to tell you what their buggiest system ever loaded onto a computer was. It’s like death and taxes.Catalina is the buggiest system I ever loaded on a computer. Small but annoying problem; Can't update Apps, can't download Apps, changes Mail.- The copy-and-paste problem seems to be caused by a font translation issue from the web page to Terminal.
The double dashes are coming out as single in Terminal with the error 'command not found'.
Replacing the single dashes with doubles results in the error 'invalid option --?'
Removing the second set of dashes finally worked for me:
... --volume /Volumes/USBdrive /Applications ...
