Download my 2GB System 6.0.8 or System 7.5.5 drive image (compressed to around 50Megs), remember not all 68k Macs support all system versions, System 7.5.5 is the most supported but requires 2MB ram minimum.

Update your SCSI2SD with the latest firmware.

These steps are a summary of the information in the sections below

A SD or MicroSD card you plan to use with your SCSI2SD adaptor.

A SCSI2SD adaptor, you MAY be able to use these images with a Compact Flash card of the correct size and a CF2SCSI adapter, if you can, let me know.

* There are some rare 3rd party upgrades that add a SCSI port to 512K systems. You will need to use one of the other setup methods I’ve previously identified, with the best option being buying and using Floppy-Emu to boot from 400KB SS SD floppy disk images. These three 68k systems do not support internal or external SCSI. The SCS2SD will work for the majority of 68k Macintosh computers except: The 128K, 512K*, 512Ke*. Note, for Powerbook systems that only support 2.5″ SCSI drives, a Powerbook Edition of the SD2SCSI adaptor can be used to replace the internal drive.

A working internal or external SCSI connection, you will need to have an SCSI enclosure or an external adapter for your SCSI2SD adaptor so to use it externally.

If your 68k Macintosh does not turn on, or does not show the insert disk icon, you may need to do some repair work before you proceed.

I’ve added an entry to my site with details of how I’ve set up a 32GB SD card for use in my Macintosh LC 475 with my Apple IIe card (4 ProDOS partitions) What you need

Note, this is one of many, many options available to you for booting your classic Macintosh. And also wipe out the system would not be a good approach for me, especially still in lock down period.So, similar to my entry on setting up using a floppy disk, and setting up using an Iomega Zip Drive, I created boot images for System 6.0.8 and System 7.5.5 for setting up an SD card for use with SCSI2SD. While I upgraded the system, I didn't backup the system, so I can't time machine it back. Therefore I had to rely on the external wifi adapter to get decent network. Even after the upgrade, the interal wifi still suffer network inconsistent issue heavly.

This is my working laptop, I had to bought this adapter after work from home period since its internal wifi is terrible. What can I do to make Big Sur work with this wifi adapter? The adapter would start to blink after plug-in in 2 seconds, yet the adapter won't be able to blink at all for the Big Sur. Either type-c port directly or with a usb to type-c converter inbetween, both ports can recognize the adapter correctly. I am able to successfully connect adapter with my other laptop. There is no issue regarding the wifi adapter itself. Nevertheless, after restarting, my extended wifi adapter still can't work. I also tried doing smc reset, nvram reset. I had tried to reinstall the driver, and even other driver from gitHub. Recently, I upgrade to macOS Big Sur (11.0 Beta (20A4300b)).Īfter upgrade, my tp-link usb wifi adapter( Archer T2U Plus model) no longer works.
