By happy accident, during a research 6 months ago,
I stumbled upon this blog post by Matt Septhon aka @gingerbreadman
- the contributor of Japanese Macintosh discoveries.

Thought I’d share it, in any case—I’m often too busy digging in the past.

That's really awesome. I wish I had an iPad Pro.

Thanks for posting the links @Cashed. I will have to give that a try. My emulated classic Mac is using UTM a QEMU wrapper and QEMU does have a heavy overhead. The Apple store does not allow emulators, so there is no way on a stock iPad to get Basilisk or MiniVMac installed. I do have a developer account and do have Xcode installed on my Mac so there is nothing beyond my laziness to keep me from giving this a try.

I have still not tried to build Basilisk for the iPad. I did get a change to try UTM/QEMU on a 2017 iPad Pro, but found it was not any faster or better than using it on a newer 9th gen base iPad. I guess that shows a 9th base iPad is about as fast as a 2nd gen iPad Pro.

Mendelson says that none of his SheepShaver/Basilisk  emulator builds will run on Macs using OpenCore Legacy Patcher. But I did discover that his OS8 build runs fine on a 13" 2015 MacBook Pro using OpenCore Legacy Patcher to run Ventura on the machine. The 2015 MacBook Pro is a dual core i5 and I can report that it does not run QEMU/UTM any better than the iPad do. I was just aware of how many resources QEMU requires to emulate hardware not native to the host machine.

You are welcome!

Thanks for all the additional shared info @wove
I'll also be taking this step on my old iPad Pro -when I've found a home and gotten all my barebones computers back out of storage.

Apologize for the 'past' links in the OP not working on legacy -my bad. Forgot that the 2nd url also has to be http as well -for it to work. Captured pages has to be from around 2013-2015 -not 2021 as in the above case.
Waiting for @MTT to scold me :D

That’s excellent news, Wove! :D how do you find Ventura with the OC legacy patcher on that MacBook? I just setup someone with with a ‘17 iMac that has Ventura and it’s a pretty solid OS, so I’d love your thoughts as to why you chose OCLP Ventura over using Monterey on it (if it’s a solid performer on your end, I might even consider getting me one at some point! :D) I have a ‘14 Mac mini that might even be a similar candidate for patching, but I’ve been just a little nervous to try it out (I’m not sure if I tried using OCLP on an older mini to try running Mojave on it, but I just got a crazy mosaic display output)

My real interest in Ventura is because it is the OS where Apple introduced the FreeForm application with MacOS Ventura and for me it has become a “killer app” that I use all the time. Ventura runs well on the 2015 MBP. It is solid, stable and reliable. However battery life takes a big hit and under the load of compiling or transcoding performance takes a noticeable hit as well.

I ended up going back to Monterey, which is supported and does very well on the MBP and is still new enough that it does already with modern web browsing, purchasing and finance things.

DosDude who started creating patchers before the OpenCore project stopped with Catalina. Being very Apple like he noted that pushing the older hardware into newer systems involves a performance trade off, and the user experience takes an unacceptable hit.

I have tried OpenCore Legacy Patcher on most of my older hardware. It is exceptionally well made software. It is easy to use, lots of fall backs to protect you from silly mistakes and in my experience if OCLP says your machine is supported, then it will work. However like with many things the fact that you can do it, does not necessarily mean you should do it.

Currently however I do not have any hardware running OCLP and have supported OSes running on them. Most of my “necessary” application run very well from Leopard to El Capitan and in fact the 13” 2015 MBP would also run El Capitan.

What software do you use to emulate Mac? Have you tried Mendelson's packages for Windows and do they work with Win 8.1? I do not have any version of Windows install, so have never given his Windows packages a try.

I have an old Windows RT tablet which runs 8.1 and I kind of liked the Metro UI. Ars gave it good reviews, but I think they were the only reviewers who thought it was good. Overall it did not receive a good reception. (I have since switched the Windows 8.1 for Ubuntu, which runs alright on the RT.)

@wove: gotcha! I figured likewise: if it ain't broke, right? ;) but now I'm curious about this latest, killer app Apple introduced and if there might be a way to jimmy it into Monterey! I did find (modern link) ExcalidrawZ which is compatible with Monterey and also has an iOS app; just wish Apple didn't prod their Mac herd to upgrade their Macs with teasers like Freeform! :) oh wait.. my iPhone has Freeform? :o oh my, I might have found my newest plaything now, and it's all you fault, Wove! :D but thanks for shedding some light on what you ultimately did with your MBP (even though an external OS boot and/or using a dual boot between volumes might even be a possibly, but then Ventura's not really part of your daily driver then, so-to-speak) :(

@snes: of the two PCs you using, I'd favor your i7 just for its speed and being far newer so more things can run on it smoothly and w/far less effort! I second Wove's suggestion of using the Mac OS app for Windows ;)

@cashed: I recall when GBM posted on his blog and mentioned it; I think my last iPad mini died a good while back, but it would have been fun to experiment with it to see how and if it could run Basilisk II, but as of right now, there are no iPads in my arsenal atm, but then, I don't do a lot of drawing, and nothing would really stop me from trying it out on my iPhone, but iirc, this entails finagling with iOS itself, right?

Curio was the application I used prior to FreeForm. Curio is a very very feature rich (and expensive) application. I first came across it using Tiger and continued with it until Freeform appeared. This is getting very off topic and I apologize for that.

I started this type of workflow using ClarisWorks back on System 6. I created a Draw document, in which one can insert a painting, text, spreadsheet/database and even using the communication module one could pull in data for remote sources. As time and tech marched on I moved to using CoreDraw 8 for much the same purposes. My interest in OpenDoc comes from the constant looking to find the integration needed to take bits and bobs and turn them into completed projects.

I have moved to newer hardware, newer OSes and newer software, but for me it has been more a progression of refining my workflow, than abandoning older trusted tools.

@cballero iOS stays intact -an app is created.

I used to do digital art on my iPhones, started on 4S, and especially on the 6S. Huge TIFF and SVG files and collaborated with an app developer on a vector app. I stopped due to eyesight getting bad.
Sure it’s possible but consider the screen size and resolution. Besides the ones I sold, I still have an old smaller iPad and the 1st Gen iPad Pro 12,9” -you can get them from $79 USD

Quote from: @gingerbreadman
Screen Resolutions

The original Macintosh had a native screen resolution of 512×342.

Conceptually, the iPad has a logical screen resolution of 1024×768, which when running in pixel doubled mode equates to 512×384. A pretty good match. Specifically, the native resolution varies according to the model of iPad or iPhone you are using.

I use an iPad Pro 12.9” which has a native resolution of 2732×2048, pixel doubled that means 1366×1024, and pixel quadrupled 683×512. Targeting this ballpark of resolution means user interface elements will be around the magic 44pt tappable area, so that fingertip interactions are accurate, predictable and enjoyable.

ps @wove I forgot to mention this yesterday. Don’t be, it's very interesting read and fits the topic.
