pkg files, inside the macos_local folder (Provide the admin password when requested): “ sudo mkdir -p. Enter the following command to create the relative path for the.Go to the newly created folder by typing “ cd macos_local” and hitting return.Type “ mkdir macos_local” and hit return to create the root directory of the same name on Desktop.Type “ cd Desktop” on the command line and hit return to enter the Desktop folder.Open Terminal from the Launchpad or Applications list.The below instructions will guide you through the set up process. Then, we’ll use macOS’ buit-in SimpleHTTP server convert the folder into a web server directory. Once the relative path has been created, we’ll configure the localhost server to point to the “macos_local” directory on Desktop. In this example, we’ll create a folder named “macos_local” on Desktop, and replicate the directory structure of the package URLs under the same. Step 3: Place the package files in a certain relative path from the localhost root, so as to mimic the structure of their respective download URLs. In that case, use the “sudo killall -HUP mDNSResponder” command to flush DNS cache. Note: Sometimes, you might need to flush the DNS cache for the changes to take effect. Press control + X (^X), then Y and hit return to save the file and return to Terminal prompt.įrom now on, any request issued for the particular root domain () from the Mac will be directed to localhost.Append the following line to the end of the file: “ 127.0.0.1 ”.The hosts file is now open in editable mode within the Terminal window. Provide the System Password when prompted.Type in the following command: “sudo nano /etc/hosts”.Launch Terminal on your Mac from Launchpad or Applications list.The below instructions will guide you to modify the hosts file as required. To do this, you need to edit the hosts file on Mac to point the root domain of the download URLs (“”) to localhost (“127.0.0.1”). Step 2: Configure your Mac so that MAS looks for the macOS packages locally instead of from the Apple server. macOS High Sierra InstallAssistantAuto.pkg file download URL:.macOS High Sierra RecoveryHDMetaDmg.pkg file download URL:.macOS High Sierra InstallESDDmg.pkg file download URL:.First I need to work up the courage to crack my iMac and attempt a video card upgrade.and, it takes a lot since I have Cerebellar Ataxia.Step 1: Download the three “.pkg” files from the respective URLs given below. Not sure if a new MacBook Pro/Air/X is in my future.might attempt another hack instead.īut, given no support for 32-bit apps in Catalina, it might be a long time before I make that leap. I was in the process of trying to find a new hard drive for it (had already gotten a new battery), and reinstall with final 10.6 (re-purchased from ebay) When, I had the darn thing stolen Since until a last year, I still had a first generation MacBook Pro (core duo). I saw that there had been patches to get 10.7 or newer to install onto 32-bit hardware.which I might have tried, if I had known about it. I'm sure dosdude1 will come out with a patch to get Catalina onto an unsupported Mac. The alternative might be to see if 3.48's calibre-debug will run the latest python code, probably depends on whether the latest can still be run with python 2.7.though thought there were framework changes as well. I briefly looked at running from source, and found the xcode project was a for a newer version than I have.not sure what it would take to downgrade the project. (I'm pretty sure I remember you saying you're not that sort of person though.) If that's okay with you and you find yourself excited by the idea of *experimenting* with compiling calibre from source, then by all means don't let me dampen your enthusiasm and feel free to hop right by the development subforum to ask questions. There's a thread in the development subforum about this - it's been suggested that you *might* be in luck if you need 10.12 support, but 10.11 is simply utterly hopeless as Qt>=5.12.x won't compile under any circumstances. In theory, it may be possibly to compile all of Calibre from the ground up, using a full blown development environment, targeting the version of macOS you need. (As in, the thing-that-doesnt-work-on-older-macOS-releases-Qt5. This does not, not has it ever, allowed you to run Qt5 itself from source. If you have a copy of Calibre already installed, containing the binary components that don't work on older versions of macOS, you can check out the calibre source code and modify the pure python components, or run against newer versions of the pure python components. It's something being said by someone who doesn't actually know what they're talking about. What does that mean? "running from source"?
