.7Z File Extraction In Mac OS 9.2.2

HI all, got a problem. I downloaded Copland D7E1 and Mac OS 8.7 "Sarah", but they are in the .7Z format, which Stuffit Expander in Mac OS 9.2.2 won't understand, and neither will the Pack-In Stuffit Expander that comes with 10.0.4. Can anyone help? Thanks!!!

I only got 50k upstream, but I could repack the files as a long term project, if there is nobody else.
You certainly tried Zip-It already, I presume.

God, I hate that 7z format. The usual linux children foisting crap off and claiming it's better because it gets 1% more compression and is "free-er" or some garbage like that.

Please, everyone, stick to standard formats - RAR, Zip & Stuffit - for anything here.

Here's another copy of D7E1 I found via Google.

This one is stuffed. I hate 7z too.

Burn yourself an ubuntu live CD, for instance:
http://cdimage.ubuntu.com/ports/releases/8.04.1/release/
This should be able to open the archive.

7z is better than RAR though. I don't want ANYONE here using RAR. 7z is great for OS X stuff, though for OS 9 and earlier stuff, please use .sit.

The Unarchiver ( http://wakaba.c3.cx/s/apps/unarchiver ) works great for RAR and 7z extraction in OS X.

I´ll upload both files as .sit right now. Will take some time...
Done.

Hope this helps, compression was done with Stuffit5.

No problem. If you would like me to re-upload some other files as .sit, feel free to name them.
It isn´t a big hassle for me and I´m online with a flatrate anyway.

Yea, if you could mirror the beta's on there that'd be wonderful. Mac OS beta's, that is. Thanks!

Do you want the ten point something files too?
I don´t know if it is a good idea to upload them to MF (or anywhere else).

One other obstacle: The 7.0 super beta is a Nero Disk Image.
Is anybody aware of a method to transform it into something more Mac like?

Please look here for latest proceedings on mirroring files from WinWorldPC:

@24Bit: If on OSX you could run it through 'AnyToISO'.

Thanks for the pointer SwedeBear!
I did it the hard way, to CD-RW with Nero then imaged it with DiskUtility.
Pretty funny idea, to save a Mac disk with Nero.

I just upped Cheetah to the folder linked above.
Please be sure to store the files you want somewhere permanently. I am not going to keep them on my Mac and I am not sure if Mediafire will leave them alone. MF never deleted one of my files so far, but I did not upload xfiles on the other hand.

All right Copland Dev. , I´ll leave that to you.

Thank you. If all goes well, expect Copland completed by 2013.

What are your plans concerning Copland in detail?
BTW:
The Pumas are on their way, deflation has been done with Stuffit7 this time.
Did you ever come across a German localized OS9.0 CD? There is a developer release with many languages floating around, but I cant find anything useful.

The Mediafire upload is complete, regarding the MacOS betas, by now.

As mentioned above, Pumas are deflated with Stuffit7, the others are Stuffit5 files.

Bigger files are in 200MB chunks, as my MF account is a free one.
Stuffit Expander should join the files again automatically while inflating them.

I'm currently trying to make it stabile. I'll be temporarily removing Mac OS 7 support, and when it's stabile, will put in OS 9 support.

Nukernel development. That sounds great! Right now, there is no good kernel out there: Mac OS X's Mach Kernel was too slow right from the beginning. The Linux kernel gets more and more unstable and messed up. Apple purchased NeXt for 400 millions and needed six years to make Mac OS X work somehow. I wonder what would have happened if they had decided to invest the 400 million and the six years into the Nukernel. I mean, it's amazing that you, Copland Dev., are able to finish the Copland project alone in a number of years - something Apple was not able to do with lots of money and myriads of developers. I hope there will be no patent right problems if your work turns out to the real good.

@Copland Dev:

Do you have any stuff we don't, or is not public? Laughing out loud

Sorry for interrupting…
I'm from the Linux/DOS/Windows/Mac OS X world and, quite obviously what I'd say from my perspective, 7-Zip is a great archiving tool. It has compression rates better than anything I know, and it is multi-platform. The problem with it is, for one, that it was developed way after Mac OS 7/8/9 was current, and that it needs really —really— much computing power and main memory.

You could say, that's the way life goes. Or, as the pirates say: Fell behind, left behind!

Anyway, it's not the .7z-format that sucks. It's just not suitable for archiving classic Mac OS applications, because there is no unarchiving tool available for it.

Using Mac OS X I can only recommend 7-Zip, because of compression rates. And, yes, there is a very very good unarchiver available for Mac OS X: The Unarchiver. I can only recommend it, also for StuffIt-crap.

Oh, yes, I hate StuffIt. At least on Mac OS X.

For Mac OS 7 – 9.2.2 StuffIt is just the way to go. Or ZIP maybe. Only disadvantage is that compression rates are really bad compared to … well, you get it.

Use the right tool for the right purpose. Don't .7z or .rar stuff that is meant to work on Mac OS!
Cheers!

The Unarchiver needs Mac OS X 10.3.9 minimum. So no 7-zip extraction with Jaguar.

There is also a command-line version: unar. I didn't test it, but it is possible that such an application could run on older versions of Mac OS X. This isn't a GUI-friendly solution, I know, but it might be a way to extract .7z files on older Mac OS X versions.

Can you test this?

EDIT: Still, this doesn't make the 7-Zip format suitable for most of what is offered here at the garden!

Tested the command-line version on Mac OS X 10.2.8. The app won't even launch. This what regularly happens to Mac OS X 10.3+ apps on Mac OS X 10.2.

I found a list of free and shareware packer/unpacker applications for both Mac OS X and Mac OS 9:
http://www.pure-mac.com/compen.html

Browsing through it, ACE may be suitable for packing Mac OS X stuff meant for 10.1+. If I remember correctly ACE has quite good compression rates compared to ZIP or SIT (StuffIt).

There are lots of GUIs for unpacking. I guess that packing is mostly on the command-line.

In order to preserve the resource fork, you can use any command-line packing tool after a piped tar stream [Edit](on Mac OS X 10.4+). On previous Mac OS X versions, tar completely ignored the resource fork. But, this has to be confirmed. Maybe there is a command-line parameter to activate it on Mac OS X pre-10.4.[/Edit]
I used this with 7-Zip:
tar cf - ./dir/ | 7za a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on -si dirname.tar.7z

This will most likely also work with a command-line version of ace and any other, if the packer can take the standard input as argument.

BTW, for Mac OS X 10.1+ there is a handy tool called Zippist for managing ZIP files (instead of SIT or BIN, as it used to be in earlier versions of Mac OS X).

[Edit#2] Typo: file extensions for archives piped from tar have to be .tar.7z or, with ace: .tar.ace

Just out of curiosity: I tested 7-Zip on my Power Mac G5 (original, 2003) 2.0 GHz Dual Processor with the Mac OS Anthology. For this I uncompressed the ZIP’s and recompressed the two text files (.txt) and the eight disk images (.cdr) into one 7-Zip archive. I used the ultra settings as described in the man page.

Wow.

It took my G5 about 6 hours to be at around 75% through. I cannot say for certain how long it took, because I left it running over night to have it finished in the morning.

Now, the result:
Uncompressed: 29.68 GB
ZIP-compressed: 26.99 GB (~91% of original size)
7z-compressed: 23.32 GB (~79% of original size, ~87% of ZIPped size)

The question is: is it worth the effort on a PowerPC system just to save additionally those 3.67 GB (~13.5%)? (It is worth it on a modern system having the power of Core i/AMD K10 and better…)

Also, the decompression is not so easy because it will only work on Mac OS X 10.3.9 and higher, and it requires additional software (p7zip via MacPorts/Fink or The Unarchiver, to name just the two).

Even when considering a faster decompression, the ZIP is just easier to handle. And if you can store 23.5 GB, you’ll also have the space to store 27 GB.

Just my 2¢.
Cheers, muttztfz

There is a ton of Mac OSs here, but NOT either Copeland or 8.7. Its an FTP site, so you could save them up there:
