ISCSI targets for the Mac
I setup a VMware vSphere 4 Server with RAID 10 direct-attached storage and 3 virtual machines:
- OpenSolaris 2009.06 dev version (snv_111b) running 64-bit
- CentOS 5.3 x64 (ran yum update)
- Ubuntu Server 9.04 x64 (ran apt-get upgrade)
I gave each virtual 2 GB of RAM, a 32 GB virtual drive and setup a 16 GB iSCSI target on each (the two Linux vms used iSCSI Enterprise Target 0.4.16 with blockio). VMware Tools was installed on each. No tuning was done on any of the operating systems.
I ran two tests for write performance - one on the server itself and one from my MacBook Pro (10.5.7) connected via Gigabit (mtu of 1500) iSCSI connection using globalSAN 3.3.0.43.
Here’s what I used on the servers:
time dd if=/dev/zero of=/root/testfile bs=1048576k count=4
and the Mac OS with the iSCSI connected drive (formatted with GPT / Mac OS Extended journaled):
time dd if=/dev/zero of=/Volumes/test/testfile bs=1048576k count=4
The results were very interesting (all calculations using 1 MB = 1,084,756 bytes).
For OpenSolaris, the local write performance averaged 86 MB/s. I turned on lzjb compression for rpool (zfs set compression=lzjb rpool) and it went up to 414 MB/s since I’m writing zeros). The average performance via iSCSI was an abysmal 16 MB/s (even with compression turned on - with it off, 13 MB/s).
For CentOS (ext3), local write performance averaged 141 MB/s. iSCSI performance was 78 MB/s (almost as fast as local ZFS performance on the OpenSolaris server when compression was turned off).
Ubuntu Server (ext4) had 150 MB/s for the local write. iSCSI performance averaged 80 MB/s.
One of the main differences between the three virtual machines was that the iSCSI target on the Linux machines used partitions with no file system. On OpenSolaris, the iSCSI target created sits on top of ZFS. That creates a lot of overhead (although you do get some great features).
Since all the virtual machines were connected to the same switch (with the same MTU), had the same amount of RAM, used default configurations for the operating systems, and sat on the same RAID 10 storage, I’d say it was a pretty level playing field.
At this point, I think I'll be using Ubuntu 9.04 Server (64-bit) as my iSCSI target for Macs.
Has anyone else done similar (or more extensive) testing?
I had a lot of trouble with SimCity4 on my iMac. It became such a headache that I returned it to compUSA. It ran very choppy and crashed repeatedly when the city began to develop. My system FAR exceeds the system requirements for the game, and after some online research I discovered that I am not the only person to have this trouble with SimCity running on 10.4. I have also read problems concerning the SIMS2. Some of what I have read indicates that 10.3 runs the games fine, but 10.4 causes them to crash. I don't know if this is the case, but I do know that I am now very weary before dropping $50 on a game that may not perform on my computer as it claims to on the box. Some people trying to run games are talking about waiting for Mac OS updates that will allow them to run smoother.

What is Apple's position on Anti-virus software for the mac?
I have started replacing my customers PCs with iMac's and Mac-Mini, and I have always operated on the assumption that anti-virus software is not necessary, but I fear that my opinion might need revisiting. So I would pose the question again, does the community and/or Apple have an opinion on the need for Anti-Virus, Malware and all the other nasty inflictions. If you, as a group or individually do recommend, what product would you recommend? Thank You --- Bill Shaw - Kansas City, Mo.
This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an attacker who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware. Starting with OS X 10.7.5, there is another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications that are downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Applications certified in this way haven't actually been tested by Apple (unless they come from the Mac App Store), but you can be sure that they haven't been modified by anyone other than the developer, and his identity is known, so he could be held responsible if he knowingly released malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe. Note, however, that there are some caveats concerning Gatekeeper:
It doesn't apply to software that comes packaged as an installer. Treat all third-party installers with caution.
It can be disabled or overridden by the user.
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to applications downloaded from the network. Software installed from a CD or other media is not checked.
For more information about Gatekeeper, see this Apple Support article. Notwithstanding the above, the most effective defense against malware attacks is your own intelligence. All known malware on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. [Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.]
“Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Java on the network (not to be confused with JavaScript, to which it's not related) is always a potential weak spot in the security of any operating system. If a Java web plugin is not installed, don't install it unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the filesystem. Malware gets into the system by being downloaded, not by materializing from nowhere.
In order to meet that nonexistent threat, the software duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability and poor performance.
By modifying the system at a low level, the software itself may create vulnerabilities that could be exploited by malware attackers.
ClamXav doesn't have these drawbacks. -
Framemaker for the Mac. WHY NOT?
I have a Mac and use the Creative Suite software on it. Yet, when I went to go find FrameMaker, I have found it is ONLY available for the PC. Why?
So I go look for a solution and find that FrameMaker 7 is the last version available for the Mac. Ok, I still have my G4 as well. So I figured I will look to get a copy of v7 then. Nope, can't find it on the Adobe site. Not only that, but it's a pain in the "blank" to find a viable copy to puchase other than on amazon for $4K.
If Adobe is going to stop making a version of their software then I can understand the cut. But to stop making it for one system and not the other? At the very least, you could continue to keep support for, and make available (at a reduced price hopefully), your older version for the Mac (or PC if you cancel a PC version of something), so that users can still use the software if they have the system to use it.
A huge amout of Mac people use your software. Apple computers are still looked at to be the BEST graphics hardware around to run. So when someone thinks "graphics" often, the Apple computer is what comes to mind. When they think Games, the PC. One is for work, the other for play, when it comes to Graphics. So, what's with cutting Apple off for FrameMaker.
So I have a suggestion/request. IF your going to keep a software package going for one system, and not the other. Then at the very least, keep the Last Version of the software for the other alive and supported.
You have FrameMaker for the PC. V12.
You stopped for the Mac with V7.
Go back and resupport, and sell V7 to the Mac folks (at a reduced price since it is older). Then, if possible, get V13 or 14, or what ever, updated to work on the Mac and PC. Then, offer the Mac folks the upgrage pricing to go from 7 to 13 (or 14, or what ever).
For those anti-mac people - For the record, I am fully experienced using both the PC and Mac. I own a mac and prefer the Mac for all my Graphics Needs. So please don't suggest I get rid of my Mac and get a PC. Won't happen.> The old Mac code is too old to port to current machines.
It's not just a codebase problem. It's a platform market problem.
Frame's ostensible competitor has a codebase that's some 15 years younger, and it's also Windows-only (and somewhat arrogantly oblivious about it - they don't even tell you what platform you must have to run their stuff).
The question becomes one of: what are the demographics of future content-creator platforms? Some of the platforms that FM used to run on (various Unix RISCs) are now entirely gone. The abortive port to Linux failed to become a product (might have been intended to fail). Desktop Mac may or may not be a key part of future Apple plans.
Windows, alas, is being massively bungled by Microsoft, who arguably accelerated the demise of the desktop PC with Windows 8. A c|net news article today is headlined "New Microsoft VP consigns the PC to irrelevance". Well, you know who to thank for that, Mr. Elop. Sure, content consumer computing is increasingly ISA- and OS-agnostic. Consumer code needs to run on ARM and x86, on at least 3 different OS'es.
Adobe is in the content creator business for revenue products. Creator development/authoring platforms are no longer the same as consumer platforms. Adobe needs to keep an eye on where this is all headed, and needs a Plan B in case MS continues to screw up desktop Windows. If CS and TS were to be ported to a second platform, it's not clear that Mac is the optimal target. It might be to Linux again (whether Android or some other distro is an open question), perhaps on ARM-64. Does Linux have CMYK model yet? or color management? -
I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?
In the Mac side of things, backups usually come in two flavors: clones or incrementals.
A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
Holler if you need specifics on how to do each. This was just an executive summary. -
I am trying to play a DVD on my MacBook Pro and transmit it to my TV (using my TV as the monitor) utilizing a VGA cable and adapter for the Mac but the only image that shows up on the TV is the MacBook wall paper, any ideas on how I can transmit the movie from my MacBook to the TV? I also tried an HDMI cable and had the same issue.
you are probably seeing the extended display.. to see ur main display go to pefrences then display steeings and turn mirroring on.
this will display ur mbp main screen. good luck. -
Office for the Mac - file open slowness, freeze, or crash
When I select the File - Open window, any of the Office programs take a few minutes to display all of my files in the Documents folder. When they are finally displayed, any attempt to scroll through the list or go to a specific file results in the Mac's spinning wheel being displayed. Quite often, nothing happens after the wheel stops spinning. Sometimes, it just continues to spin. Consequently, it is almost impossible to use the File - Open window in Office to select a file to open. The only way I can do so is to use Finder to display my files in the Documents folder and then selecting them in that program's File - Open window.
When the wheel is spinning, Force Quit says that the specific Office program being used is "not responding." Usually, I use Force Quit to close down the Office program if it has frozen, crashed, or been slow using the File Open window.
I spent an hour yesterday with Microsoft Support on the problem. The conclusion of the tech was that I had too many files in my Documents folder. I pointed out that other programs such as FileMaker Pro didn't have this problem. The tech's response was that Office has to scan the entire Documents folder every time the File Open window is opened, but that FileMaker Pro stores a list of the last files in the Documents folder and doesn't rebuild the list every time.
I am skeptical of this "answer." The problem didn't exist until a few months ago.
My computer is a MacBook Pro 2.3gHz with 16 GB of RAM and a 750GB hard drive which has about 500GB free. This is a fairly fast machine with a Geekspeed of 10688. I was running the latest Mac OS Yosemite 10.10.1. The problem first surfaced with Office for the Mac 2008 about 3-4 months ago running Mac OS 10.10.1. I installed Office 365 yesterday, and and Mac OS Yosemite 10.10.2 today, and nothing changed.
The only solution that I know of is to take a lot of time to segregate my files in the Documents folder into more subfolders (I already have quite a few). That I am loath to do, because the solution doesn't work very well. It takes about a minute to select a subfolder in the File Open window, and then about another 30 seconds before Office allows me to scroll through a relatively small number of files (e.g., 100 files) in the subfolder.
When this question was posted to the Microsoft Community, I was directed to an article talking about problems with Office and Mac OS. None of the solutions worked, probably because the article considered only Office X and Office 2004 for the Mac and OS 10.2 and 10.3.
Help, please!1) Verify that Office is fully updated. v14.4.7
2) I suggest you run Font Book and vailidate your Fonts. Microsoft installs duplicate fonts and after you clean up your fonts, this has often fixed odd issues with Office.
Office 2011 Duplicate Fonts to Delete
3) Delete the com.apple.LaunchServices file in your User's Library/Preferences folder. Log out under the Apple in the Menu bar and test. More info
If this fails to fix....
Testing in a new User will quickly tell you if the problem is system wide or if it's your User's folder that contains the problem.
Put a few test files in the Shared folder. Data in the Shared folder can be accessed by another User. When you "Switch Users", you can access the files in the shared folder. After you log into the new test User, drag from Shared (it actually copies). Put the test files in Documents.
Open Word. It won’t be in the Dock in the new User. Go to Applications to open.
Do you still see the issue?
If yes, you can eliminate the number of files in your Documents folder.
If no, then you might want to do a clean up in Documents.
*Remember to drag files back from Shared when you log into your main User.

I am a teacher who would love to create the game "who wants to be a millionaire" with my own questions. I would use this for test reviews. I can't not find something for the mac. It is out there for the PC, but my class room is mac based. I can't use anything that will allow me to run the mac in windows, either. Anyone know of a software that will allow me to input my own questions? Thank you very much for your time and consideration.

How can I get qucken data from windows copied over to quicken for the Mac?
I recently bought a Macbook Pro. I have been using windows my whole life. I installed Quicken 2006 for the MAC. I backed up my windows quicken on a disk and it just doesn't open it. Is there a trick? or am I screwed?
Unfortunately, there is no simple way to convert a Quicken/WIndows data file to Quicken/Mac. This is a major complaint of a lot of switchers.
I can't find the link (I'll keep looking) but I know that Intuit offers a conversion service. You send them your data file, and for an absurd amount of money they'll convert the file for you.
You're probably better off starting your Quicken/Mac file from scratch.
That's what I did. It took some time to do, but now I'm happy with it and I didn't have to pay anyone to convert the file. -
I have iMovie 09. I just erased my external hard drive, but it is still formatted for the mac. However, iMovie will not recognize the hard drive. It shows the only hard drive available is the computers. How do I get the external hard drive to show up?
In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.
If it does contain data...

I have Photoshop CS2 for the MAC and it stopped working on my MAC. I recently bought a new MAC, an IMAC and it doesn't work on that either. There appears to be no way to contact Adobe. What do I do? Thanks, Ed
That because the activation servers were retired. Now for the good news:
Adobe has provided a non-activation version of Photoshop CS2 free of charge for their CS2 license holders.
Download the Mac version of Photoshop (not the suite) and copy down the serial number next to it. Do not use your original serial number or cs2 disc.
Download Acrobat 7 and CS2 products
Uh... one more thing CS2 is PPC only. OSX 10.6.8 has Rosetta to run legacy PPC products. 10.7 and above will not.
Good luck,

Adobe Acrobat 9 Standard for the Mac?
Okay, I apologize for what may appear to be a frightfully stupid question, but is there an Acrobat 9 Standard for the Macintosh? There appears to be support files and such for Adobe 9 Pro for the Mac available, but whenever I search for the Adobe 9 Standard, all I can seem to come up with is the Windows version...?
If not, and if for some unknown reason, they aren't updating the two version numbers in sync with each other, what's the most recent version of Acrobat Standard for the Mac? Or will I be stuck with 9 Pro as my only option, and end up having to pay for the additional features I don't need?
Steve MHonestly, if you are creating a PDF, say in a Business setting, to go on a website. Except when it specifically meant to go to a Printer. Do you need the Print Press Stuff??
More bang for the Buck would create a Version For Print press industry.
Then Have then the pro version have the PDF forms Creation stuff that available in PC only now.
The feature set that was in Acrobat 5 is a much better fit. If someone need Print Press features sell it as a $50.00-100.00 add-on.
There are some features related to Print press I never have used. But I got them because I needed forms creation for the Web. -
