Anyone else noticed huge speed decrease of Adobe Flash player 10,0,32,18 in SL. In Leopard that version was ok, only ok comparing it to windows. About Adobe Flash Player for Mac The Adobe Flash Player is a widely distributed proprietary multimedia and application player created by Macromedia and now developed and distributed by Adobe after its acquisition. On my old imac G5 running leopard and my new imac running snow leopard using FIREFOX but NOT SAFARI. There is just a blank area where the webcam should be. I loaded the latest adobe flash 10 download but it still DOES NOT WORK.

If you don't have an Intel Mac running OS X 10.6 Snow Leopard or later, you can also download Adobe Flash 10 for PPC Macs and Adobe Flash 9 for Mac OS X 10.1-10.3. It does appear to be Flash/Snow Leopard related. I have noticed video playback stuttering on my Mac Pro 1.1 with the stock GeForce 7300 GT video card that was never there before. If you watch Activity Monitor when you play back a Flash video in 10.6 you will note that the CPU demands have increased by quite a lot over what they were with 10.5.

Jeffrey Czerniak answers my “What should Apple have done differently?” question:
John Gruber’s latest piece of Apple apologetics concerns the factthat Apple shipped a known-vulnerable version of Adobe Flash Playeron the Snow Leopard DVD. He has the gall to ask those of us whoconsider this a bad thing,
But what exactly should Apple have done differently?
Gruber apparently considers the possibility of postponing therelease of Snow Leopard in order to coordinate with Adobe to beunreasonable. If postponing Snow Leopard is out-of-bounds, then Ihave another suggestion:
Apple could have posted a security advisory.
Is it possible in the run-up to going GM that a serious issue could be discovered that would warrant postponing the release of a major OS update? Sure. That’s exactly why GM releases aren’t rushed. Is this Flash situation such an issue? I believe not — and have seen no evidence that it is.
As for Apple issuing a security advisory, sure. That would be nice. But that’s not how Apple rolls. Apple’s policy regarding security issues is not to publicize them until after they’ve been addressed by software updates. It’s not unreasonable at all to disagree with this policy, but I think Apple is pretty happy with how it’s worked out for them so far, so don’t hold your breath waiting for it to change.

Why Doesn’t the Snow Leopard Installer Do the Right Thing if You’ve Already Installed the Latest Version of Flash?
Mike Ash — on Twitter here, here, here, and etc. — argues that the problem is specifically the issue of the installer downgrading the version of Flash for users who manually upgraded to the latest version of Flash while they were on 10.5. (Forgive him for his brevity, given the constraints of Twitter.)
I have no sympathy for the argument that Apple should have included an eight-day-old version of Flash in the Snow Leopard installer, or that they should have delayed the release of Snow Leopard to include it. I do have sympathy for the argument, like Ash’s, that the installer ought not replace a newer version with an older one.
And there’s a good — but, alas, in my research, unanswered — technical question as to why this did not in fact work as Ash and others expected. The Mac OS X Installer system relies on “bill of materials” bom files. From the bom man page:
The Mac OS X Installer uses a file system “bill of materials” todetermine which files to install, remove, or upgrade. A bill ofmaterials, bom, contains all the files within a directory, alongwith some information about each file. File information includes:the file’s UNIX permissions, its owner and group, its size, its timeof last modification, and so on. Also included are a checksum ofeach file and information about hard links.
The bill of materials for installed packages are found within thepackage receipts located in /Library/Receipts.
In theory, the Snow Leopard installer could look at the bom for Flash and, if the installed version is greater than the version in the installer, leave it. I do not know why it doesn’t work this way. Perhaps the bom file left by Adobe’s Flash installer is malformed. Perhaps (and this is my guess) the installer for major OS versions does not check for such things for components in the “Essentials” and “BaseSystem” installer packages. (Flash, and all other default items in the /Library/Internet Plug-Ins/ folder, are part of the Essentials package.)
Yesterday, as a hypothetical example, I wrote:
That’s just how the installer works. The same is true for anycomponent you manually upgrade. Like, say, if you overwrote thesystem version of Python with version 2.6.2 — when you upgrade toSnow Leopard, the installer will give you the system standardversion (2.6.1).
Update 1: Correction, ends up I was right in the first place. Lundell’s personally updated version of Python 2.6.2 was, and remains, in /usr/local/bin/. The system version of Python (version 2.6.1) is right where it should be in /usr/bin/. The confusion arose because he checked the version by typing just “
python -V
”, rather than specifying the full path to /usr/bin/python
at the command prompt.(As for why the Mac OS X Installer might be designed to overwrite components like Flash in this regard, consider the following hypothetical. What if the very latest version of Flash worked just fine on Leopard but did not work on Snow Leopard? That is apparently not the case, but, what if it were? (And don’t tell me it’s not possible.) In that case, if the OS installer worked as Ash and others desire, after upgrading to Snow Leopard you’d have a system where Flash did not work at all. Some people may reasonably argue that they’d prefer a broken version of Flash than a potentially vulnerable version, but the point of the components in the Essentials package is that Apple deems them, well, essential. The installer logic for these “essential” components may reasonably be that it’s going to install its own known versions no matter what’s already on the disk being upgraded. Why Flash is deemed essential is a good question, though.)
Which Vulnerabilities Apply to Flash Version 10.0.23.1?
Lastly, I’ve been attempting to research exactly what the vulnerabilities are in Snow Leopard 10.6.0’s version of Flash, but have come up empty. There are three versions of Flash to keep in mind:
- 10.0.32.18 — The current version of Flash 10 from Adobe.
- 10.0.23.1 — The version that ships with Snow Leopard 10.6.0.
- 10.0.22.87 — The version of Flash Adobe identifies as having “critical vulnerabilities”.1
Adobe’s security bulletins and advisories page lists just four advisories for Flash Player 10. One dates back to February and is no longer relevant; the other three were from late July. One of the advisories from July is specific to Windows Internet Explorer. The other two apply to Windows, Mac OS X, and Linux.
Advisory APSA09-03, dated 22 July 2009, states:
A critical vulnerability exists in the current versions of FlashPlayer (v9.0.159.0 and v10.0.22.87) for Windows, Macintosh, Linuxand Solaris operating systems, and the authplay.dll component thatships with Adobe Reader and Acrobat v9.x for Windows, Macintosh andUNIX operating systems. This vulnerability (CVE-2009-1862) couldcause a crash and potentially allow an attacker to take control ofthe affected system. There are reports that this vulnerability isbeing actively exploited in the wild via limited, targeted attacksagainst Adobe Reader v9 on Windows. […]
Advisory APSB09-10, dated 30 July 2009, states:
Critical vulnerabilities have been identified in the currentversions of Adobe Flash Player (v9.0.159.0 and v10.0.22.87) forWindows, Macintosh, Linux and Solaris operating systems, and theauthplay.dll component that ships with Adobe Reader and Acrobat v9.xfor Windows, Macintosh and UNIX operating systems. Thesevulnerabilities could cause the application to crash and couldpotentially allow an attacker to take control of the affectedsystem.
Adobe recommends users of Adobe Flash Player 9.x and 10.x andearlier versions update to Adobe Flash Player 9.0.246.0 and10.0.32.18.
In both advisories, the “affected software versions” are listed as “Adobe Flash Player 9.0.159.0 and 10.0.22.87 and earlier 9.x and 10.x versions”. So both of these bulletins mention version 10.0.22.87 as being vulnerable and recommend updating to version 10.0.32.18. But neither mention version 10.0.23.1 at all.
Is version 10.0.23.1 susceptible to the same “critical vulnerabilities” as version 10.0.22.87? I can’t find any version information about Flash 10.0.23.1 whatsoever. It could be that 10.0.23.1 has all, some, or none of the vulnerabilities in version 10.0.22.87. I do not know.
The only mention from Adobe regarding Snow Leopard’s version of Flash is this post on the Adobe Flash Platform Blog by Tom Barclay, which reads in its entirety:
The initial release of Mac OS X 10.6 (Snow Leopard) includes anearlier version of Adobe Flash Player than what is available fromAdobe.com. We recommend all users update to the latest, most secureversion of Flash Player (10.0.32.18) — which supports Snow Leopardand is available for download fromhttp://www.adobe.com/go/getflashplayer.
So, yes, Adobe clearly recommends upgrading to 10.0.32.18, but doesn’t mention any specific problems with 10.0.23.1.
Update 2: Via Twitter, Dj Walker-Morgan reports that version 10.0.23.1 is the same version of Flash from the June WWDC seed of Snow Leopard, so it almost certainly doesn’t contain the fixes for the issues Adobe publicized in July.
- 10.0.22.87 is, in fact, still the standard version of Flash in Mac OS X 10.5.8. ↩︎

With vulnerabilities here and there, left and right, it’s understandable if you’d want to get rid of the Adobe Flash Player altogether. If you can live without content running Flash, by all means, uninstall the runtime program. Doing so is the best way to protect yourself against zero-day vulnerabilities that seem to occur once or twice a month.
Good thing, uninstalling Adobe Flash Player is quick and easy.
Uninstall Adobe Flash Player from Mac OS
- Determine your Mac OS version by clicking the Apple icon in your screen’s upper-left corner.
- Run the compatible uninstaller. There are two versions available, one for Mac OS X 10.1 to 10.3 (Puma, Jaguar, Panther), and another for Mac OS X 10.4 and later (Tiger, Leopard, Snow Leopard, Mountain Lion, and Mavericks).
- Download the right uninstaller.
- Once downloaded, search for the file and double click on it to start the uninstallation process. In Safari, click on Windows > Downloads to find the downloaded uninstaller. In Mozilla, look for Tools > Downloads. In Mac OS X 10.7 (Lion), look for the Download icon on the browser, which is an arrow pointing down, and click on it to show the most recent downloads.
- Once double-clicked, the uninstaller will then start. Click Uninstall when prompted.
- Close your browser when prompted, so the uninstallation will continue.
- Once uninstallation is complete, click Done.
