It goes without saying that most of us use Mac OS X Leopard regularly and leverage its great features constantly. However, there are certain elements laced throughout the overall user experience that have always personally bothered me, like:

- A much lengthier OS install and update process than Tiger

- Convoluted post-install optimization techniques with varying results

- The need to acquire apps, files, and other noteworthy downloads from several different places on the Web

- Higher process count, and therefore usually higher idle CPU / RAM usage than Tiger

- Slower overall system performance than Snow Leopard

- The mere fact that Snow Leopard was never released for the PowerPC architecture

So, mainly as practice for something else, I decided to begin work on something much more unified to streamline and polish the core Leopard experience, which the concept of has been on my back burner for years, and although was partially realized in the past through the forms of AuroraTrimcelerator and AuroraSuite, I believe is finally being fully fleshed out now.

Mac OS X Sorbet Leopard Flaired Edges Titles.png


Introducing Sorbet Leopard - 10.5 Reinvigorated.

Sorbet Leopard can be thought of not only as something of an OS X distribution, but also as a 10.5 and 10.6 hybrid, being built off the rock-solid foundation of 10.5.8, but with certain concepts, elements, and components also transplanted from 10.6.8. Unlike vanilla Leopard however, Sorbet Leopard will boast the following system refinements built right in:

o Faster graphical performance in select system applications

o Faster network performance in all system operations

o Better disk and memory performance over long periods of time

o PowerPC-optimized code system-wide

o Reduced idle CPU usage

o Reduced OS size

o QuickTime 7.7 Pro, WebKit 604, and Bash 4.3 and additional media codec libraries built-in

Also unlike vanilla Leopard, Sorbet Leopard will as of now bring the following new features and enhancements to the table:

o A fully-featured live environment to boot into via FireWire or USB for performing administrative tasks separate from the startup disk

o A featherweight app store

o An accessible switch panel for quickly controlling various system functions and advanced settings without needing to manually resort to the command line

o Restored support for the Harmon Kardon iSub 2000


o Full support for the Apple Magic Mouse + Momentum Scrolling

o 10.6 desktop pictures, dictionary definitions, and more

o Readily themeable to newer OS X appearances right out of the box

o Toggleable ad, tracking, and fingerprinting domain blocking system-wide

-

In a departure from previous software releases, Sorbet Leopard will progress under an open development model, meaning anyone with hardware that meets the below system requirements and wishes to help beta test, bug fix, or tweak incremental builds from now until the final release has been made publicly available is welcome to do so by directly requesting to partake in a group private message for development coordination.

Additionally, certain milestones will be occasionally posted both here and at the Macintosh Garden sister thread for public review as new components are implemented and continually refined for assured reliability.

Sorbet Leopard will require a PowerPC G4 7450 processor or better, 1 GB RAM minimum, and a Core Image-capable graphics card (GeForce 6200 or Radeon 9550 and up) for best results. A USB 2.0 interface is strongly recommended.

A final release will be made in Fall 2021.

@TheShortTimer Typically, yes.

@casperes1996 Nothing of release quality has been done yet. However, most of the steps to materialize the above outlined results have already been planned in detail, so now it's just a matter of setting the concept into motion. As they are completed, all outstanding performance-related additions and modifications will be shared here over time, and once the final product is ready, a complete list of all changes made will be published for review.

Doesn't Apple's WWDC21 banner look strikingly reminiscent of Leopard's default wallpaper?

Running and posting standardized benchmarks on a standard Leopard install and an install of your tweaks is the only way to give the above sales pitch any teeth.

Wow! Leopard is slower than SL? o_O

In my experience, Leopard is significantly slower — both from the Intel Mac angle and also running the early builds of Snow Leopard (10A96) on an A1138 PowerBook G4 with 2GB RAM and an SSD (and having an identical-spec 2GB RAM and SSD-equipped PowerBook G4 — A1139 —running 10.5.8). Snow Leopard was an under-the-bonnet refinement of the work begun with Leopard, and this is evident even in its earliest (even if buggy) iteration.

I would be happy to beta test this on my 1ghz Titanium and also DLSD 15 inch. This will prolong PowerPC capability even further. I welcome this with open arms. Count me in also :)

Has anyone benchmarked Snow Leopard PPC against Leopard or otherwise compared performance?

I haven’t considered to test SL-PPC with GeekBench or Xbench because these are generally OS-independent and test processor/memory/disk-related hardware functions.

What standardized test would focus on the operating platform and not solely on the hardware?

Maybe browser benchmarks? Transcoding video times, CPU use whilst watching video, gaming framerates?

Perhaps. Video playback would depend entirely on whether benchmarks use the same parameters for both versions of OS X. Because of Snow Leopard’s (when run on PowerPC Macs) limited hardware video decode capability for AGP GPUs (only a handful of NVIDIA cards, at most), the tests would need to run side by side with software acceleration.

Even so, I’m going to run a set of Geekbench 2.2.7 benchmarks, side by side, for each of 10.6 (10A96) and 10.5.8, from the same PowerBook, running from the same SSD (in two, equally-sized partitions), and running 2GB of RAM. Three benchmark/stress tests per OS can provide an average. I’ll post the raw results to the Snow Leopard for PowerPC thread.

[UPDATE: here’s a link to those results.]

already using it but cant do much since i cant code

I can’t code my way out of a shoe box.

Interesting results. Would you say Snow Leopard feels perceptibly faster or is it difficult to say as fresh installs usually always feel faster?

I can’t speak to that directly since the 10A96 build I’ve been running on this PowerBook (I re-installed on 1 May 2021) dovetails in all the testing I’ve done with the system — namely, bringing in selected kexts from 10.5.8 (which chronologically came out later) and moving in Frameworks which A) don’t break the system and which B) restore functionality (for things like QuickLook, or running the iSight FireWire camera in QuickTime 7.7.0).

Overall — both in the May 2020 and the May 2021 installs of 10A96 I’ve run, there are several minute but perceptible improvements in the UX with 10A96 which feels a tick clunkier with 10.5.8 (which is what I run on my PowerBook5,9, also 2GB and with an SSD). To put it another way, I now prefer picking up and browsing with the 10A96 Build on the PowerBook5,8 than with 10.5.8 on the 5,9.

Finder on 10A96 does have its issues of being an incomplete work (which I can mostly get used to, even if some of them can be annoying). In addition, 10A96 doesn’t enjoy the HFS+ compression which was a cornerstone of the retail Snow Leopard (its earliest appearance being in Build 10A190, which I’ve basically avoided using so far for a list of reasons, the amount of UB code stripped out being at the top). Even with the “alpha” nature of 10.6 at this early juncture, there are paradigmatic steps forward which help with the overall UX (slightly higher contrast in UX elements, tighter list view in Finder windows, and so on).

An overall conclusion, having used 10A96, is Apple could have built and carried out a Univeral Binary of Snow Leopard all the way through 10.6.8, and the later PowerPC Macs would not have suffered a penalty in the slightest; on the contrary, they probably would have benefited from the tidier code (at least at the 32-bit level).

Great news! I'm really looking forward to the live environment, this will be really cool.
