General question about file system of MAC OS

hello,
I like to know the difference  between  HFS+ and HFSX  , I never used MAC in my life but now I have some interest.
I looked in wiki but there is no clear explanation.
thanks
johan

I've never heard of "HFSX" unless you mean HFS Extended (or more correctly Mac OS Extended), which is the more current term for HFS+.
Regards.

  • General Question About Compressor Speed & Newer Macs

    Hi,
    I am considering buying a PowerMac G5/2.3 dual-processor. I currently have a G4/350 with a 1.2 Ghz Sonnet processor installed. My main intent is to speed up MPEG2 compression for DVDSP 4 at any encoding setting compared with what I have now. I usually leave this computer running overnight to encode without any other apps running. Typical video length is 1-2 hours.
    Will I see a significant speed boost with the G5 and a comparable amount of ram or is it a waste of money? DVDSP simulation also looks choppy. Will that smooth out?
    BTW, I have no interest in creating a cluster to hand off Compressor tasks, so that path will play no part in my decision. Thanks for any help.
    James

    You'll see a difference, for sure.
    I work on a Dual 1.42 G4 tower but often visit a friend over at a local post house who works on a Dual 2.5 G5. His machine is significantly faster than mine - I'd say about 40% faster. (and yes, I say this having needed to work on Compressor on his machine)
    Considering the greater horsepower difference in your scenario, you should be pretty happy.

  • Newbie question - general question about e-mail sync

    Hi,
    I have a general question about email sync and BlackBerry smartphones.  Are there any devices that allow email syncing with a Microsoft Exchange 2007 system that do not require the BlackBerry Enterprise server?
    Thanks; sorry if this has been asked before but I was unable to find it in the forums, documentation, etc.  Everything I found assumes that for this kind of environment you will be using a BlackBerry Enterprise solution, but I can't assume.
    Thanks again.
    Solved!
    Go to Solution.

    Hi and Welcome to the Forums!
    If the Exchange server has anything that faces the internet (OWA, POP, IMAP), then BIS can be used to handle email (only email...calendar and contacts require BES to sync OTA).
    Or, a PC, inside the network (but with an internet path) and logged into the email server (using Outlook), can be left running, using the RIM Desktop Software's Desktop Redirector capability to forward  messages to the BB.
    Those are basically the options.
    Hope that helps! Let us know!

  • General Question about SAP Documentation. Where to find?

    Hello,
    I am relatively new in the SAP business and so I have some general questions about the SAP Documentation.
    Often internet-links like
    http://help.sap.com/printdocu/core/Print46c/en/data/pdf/FIBP/FI-AP-AP-PT.pdf
    are posted here by group members.
    But where do these group members find these documents?
    All I can see at help.sap.com is IDES (the model company created by SAP)and the WWW-version of the SAP-Bibliothek.
    Were can I find these PDF-Files?
    I would appreciate any hint and tip!

  • General question about iTunes Match and multiple libraries

    Hello to everyone,
    I have a general question about the iTunes Match service, which is available since yesterday in my country (Italy). Currently my library situation is the following:
    Computer A (desktop, Windows 7): "big" iTunes library (about 20 GB), at the moment not associated with my Apple ID
    Computer B (MacBook Air 2011): "small" iTunes library (about 5 GB), associated with my Apple ID
    At the moment, both my iOS devices (iPhone 4 and iPad 2) are synchronized with the smaller library on the MacBook Air.
    Question is as follows: should I subscribe to iTunes Match, would it be possible to upload the "big" library (provided I associate it with my Apple ID) to iCloud while keeping my devices synchronized with the "small" one?
    Ideally, at the end of the day, the situation should be the following: both iOS devices with music from the small library + possibility of downloading songs from iCloud (coming from the big one). Is this possible?
    Maybe the question sounds stupid, but I want to be sure about this before paying for the service.
    Thanks a lot.

    Yes, you could also associate your larger library with iTunes match if you associated your Apple ID with it. However any purchases in the library made from another Apple ID will not be matched with iTunes much.
    If both libraries are part of iTunes match, then all your devices will see all of the content from both libraries, which content you choose to have on those devices and which you have accessible via iTunes match is entirely up to you.

    Hi.. Philip...
    During installation when it prompts / gives us to  type / Browse the installtion sources like installation master / ker cd's / installation export .......,
    What did you do ?
    did you browse to the respective directory ??
    or
    did you manually type ??
    I got the same problem on unix like. On oversight instead of browsing i typed manually and by mistake in one of the path i added space in one of the installation source path and installation ended with not able to locate file system error.
    if you have typed it manually .. i beleive it could be similar to this ??
    Update your reply

    Edge Animate doesn't support css3d natively, but you can use a third party library such as edgehero.js to make this work.

  • General question about Mac hardware

    Hello. I have always used Windows. I am considering picking up a used Macbook. I have some questions about hardware. Chiefly, is there a specific reason that Apple is still dedicated to the Core2Duo processors, even in the highest-end Pros? With the advent of the Intel Core i3, i5 and i7 processors, many PC laptop manufacturers have embraced them, especially the better mainstream manufacturers, like Sony and Toshiba. I know a lot about Windows, but I don't know much about OSX.
    Is there something in the software that allows for a Core2Duo on OSX to run as efficiently or more so than an i3 or i5 on Windows 7? As it stands, comparing strict hardware profiles (processors in particular) between what appear to be equivalent current Macbooks and Windows 7 PCs, the Sonys and Toshibas seem to have a distinct advantage.
    Sorry if this is a tired question or whatever. Believe me, I'm not asking "WHAT'S BETTER? A MAC OR A PC?" Really.
    Many thanks to anyone who can point me to an answer.
    Chris

    Well, as to if there is anything that makes OS X run better on the C2D rather than a i3 or i5. I have never use an i3 based computer, but the i5 mac I used was very fast (tried the i5 27" iMac). I don't know why they are currently still using the C2D over that. I can say that the i5 didn't feel any faster, even the quad core Mac pro didn't feel faster. The main advantage to more cores will be in doing more at once. This makes the biggest difference is seen when running things like video editors. There is also a lot more to making the computer fast than just the CPU, the chipset, system bus, video card, and hardware controllers all make a huge difference. Apple has always used very good quality hardware, there have even been times where MacBook Pros have been rated as the best laptops to run Windows. But OS X will run faster on the same hardware because it is a more streamlined OS that uses the hardware more efficiently. Apple works hard to make the OS work as well as it looks, and Snow Leopard runs very well on the current hardware. I have no doubt that Apple will in the near future come out with something newer and better, but my guess is as good as anyone's as to what chip they will use.

  • General Questions about BI

    Hello,
    I want to get into SAP BI and have some questions about it.
    Is there a big downside in installing only the BI components without the Java BI components, or is it even possible if you want to work with BI. What are the general differences between BI and Java BI?
    I think the main aspects i will work with will be data warehousing and some basic reporting.
    The reason why i'm asking is that i want to run the BI components in the same system as the ECC Server (its just a test system). I read that the Java BI component needs EPC and EP and that would probably be too much for a single system (6 GB RAM).
    Thanks a lot in advance,
    Martin

    Thanks for your hints, they were really helpful.
    As i mentioned i mainly want to work with the general Data Warehouse and Reporting capabilities, so i think it should be okay.
    Actually i'm planing to write about BI and SAP within my master thesis.
    Another question, what will be with SAP BI in the future regarding the Business Object acquisition? Is there still any point in learning SAP BI or will SAP BI disapear in the future? I heard that the basic BI functionality (e.g. Datawarehouse ) will still be used but the reporting capabilities  would be disappear. I'm not sure if that is right and i'm really new to this topic. So any comments are welcome.
    Thanks,
    Martin

  • Odd question regarding files on a mac-formatted external drive...

    I have recently purchased a Western Digital external HDD (1TB) and have synced it with my mac as a time machine.
    I have also, however, moved a bunch of files from my macbook, including family movies, DVD's I've ripped, a lot of my music collection, work files and some games.
    This has worked brilliantly thus far.
    BUT! I have my MBP bootcamped for some boring programs for work etc. but want to be able to listen to music/play games/access files through the WD HDD... This may be obvious to many people; but it wasn't immediately obvious to me: Because the External drive is formatted for Mac, as well as 'time machine-d', it refuses to be recognised by the PC...
    Thus, my question is:
    Is there a way to move files from Mac to PC (bootcamped) through an external drive that is formatted to the Mac.
    If not, is there a way to move files from Mac to PC through the bootcamp disc on the Macintosh Desktop. I understand that files smaller than 4 gigs can be moved across NTFS (?) but some of the files for my work stretch as far as 11 gigs...
    Any help with this would be greatly appreciated! I've been looking around the net for the past week... It's time to be proactive...
    If any more info is required, please let me know.
    Ollie.

    Hi Ollie,
    with the BootCamp 3.0 Drivers Apple introduced a read access from BootCamp Windows to Mac OSX partitions, but this seems to only work with internal harddisks not with external ones.
    MacDrive is the choice get full read and write access on Mac OSX partitions/harddisks while in Windows http://www.mediafour.com/products/macdrive/
    For a simple read-only access HFSExplorer can be used http://hem.bredband.net/catacombae/index2.html
    The 4GB size limitation is only active on FAT32 file system not on NTFS, but Mac OSX itself can only read from NTFS partitions not write to them without additional helper like NTFS-3G http://macntfs-3g.blogspot.com/
    So, with you scenario (external HD = MacOS file system) it seems that MacDrive would be the way to go.
    Hope it helps

  • Asking general questions about 'computing' matters.

    Hello
    I'm new to the Mac world - I posted my first question on the forums today!
    I have reviewed the discussions site - everything seems very specific to apple products. Where, if anywhere, could I post a general question - like this one:-
    I have a notion that when one connects to a server directly (Usenet newsgroups for example) one makes a deliberate 'hole' in one's firewall, be it software or simply because one is using a NAT router. Sending messages to and receiving posts from Usenet is far quicker than using email, so I'm fairly confident that this is so.
    I am well aware that any URL one visits can instantly determine much information about the connecting machine. (see http://www.browserreport.com/ as an example).
    Anti-malware programs can only detect known viruses and spyware - I see no reason at all why, once one has granted a direct connection facility, between a group on a private server to
    one's own machine, malware could not relatively simply be injected onto one's computer.
    If the malware was currently unknown, how would one ever know?
    Thanks in anticipation of a helpful response

    Excellent!
    I have reviewed the discussions site - everything seems very specific to apple products. Where, if anywhere, could I post a general question - like this one:-
    Unfortunately, not in this forum. This forum is specifically about the discussion forum itself. It is kind of like a meta-forum. Hopefully, the moderators will just move your post somewhere more appropriate. (As indeed they just did!)
    I have a notion that when one connects to a server directly (Usenet newsgroups for example) one makes a deliberate 'hole' in one's firewall, be it software or simply because one is using a NAT router.
    Kind of and kind of not. Firewalls are greatly misunderstood. But essentially, yes, any internet connection you establish has some risk involved. However, the risk of making an outgoing connection is infinitesimally smaller than setting up a server to let hackers bang on 24x7.
    Sending messages to and receiving posts from Usenet is far quicker than using email, so I'm fairly confident that this is so.
    Really? I don't think so.
    I am well aware that any URL one visits can instantly determine much information about the connecting machine. (see http://www.browserreport.com/ as an example).
    Not really. It depends on what you are doing. You always give away your IP address, unless you are behind a proxy. In that case, you give away the proxy's IP address. But the proxy still knows who you really are.
    If the protocol in question supports such information, then it can be determined. A web browser does send some information about you, but you can easily change it and masquerade as some other browser. With other protocols, it isn't so easy to tell what kind of OS or software is being used.
    Anti-malware programs can only detect known viruses and spyware - I see no reason at all why, once one has granted a direct connection facility, between a group on a private server to
    one's own machine, malware could not relatively simply be injected onto one's computer.
    If the malware was currently unknown, how would one ever know?
    You wouldn't
    Don't grant anyone direct connection to your machine.

  • General question about Mountain Lion

    I've kept clear of Lion on both my MACS because of all the "bad press" it got, I'm still running Snow Leopard on my MACS and I've never had a day of problems with either. Also I run Logic Studios on both my MACS and didn't want to chance having issues with interface compatability, lack of drivers and such. My question is kind of simple and for better or worse comes down to opinion, what is the general feeling about Mountain Lion? Is it a big improvement over Lion? Is it more stable with less bugs? Any issues running Logic? I'm "playing with the idea" of upgrading but I want to do my research first. If Mountain Lion is not a big improvement over Lion or if people are having issues with running Logic I'm going to stick with SL.
    Thanks for your opinions in advance.

    Be cautious about listening too much to replies you're likely to get. These sort of questions in a place like this are like magnets to people who are having problems and want to complain about it. You're likely to hear some horror stories that don't represent the majority of cases.
    ML has been excellent so far for me, faster than Lion and no serious bugs I've discovered so far. But if you upgrade, be sure to do your homework: backup, check compatibility of all your software (including things like printer drivers) and repair the hard drive with Disk Utility before installing.

  • ANOTHER Question about my iMac G3. Mac OS X and RAM

    Hey, I have ANOTHER question about my iMac G3.
    I know that I'm supposed to have the latest firmware updates for my iMac G3 running OS 8.1, which I do, but I read some where these firmware updates could only be updated if you're running OS 9.2. Yet when I run the firmware updater, it says my firmware is up to date. I just wanted to make sure this was correct because I just ordered an OS X 10.2 CD today, and I don't want my mac to be "dead" when I install it.
    My next question is how much RAM can my mac hold. It's an iMac G3 with a 233 mhz processor, if that makes a differemce.
    Again, thanks to the people who have helped me with my first Mac.

    hi there--
    unfortunately you require system 9.1 or 9.2 for the required firmware update 1.2 for your computer http://docs.info.apple.com/article.html?artnum=86117. so you'll have to install that if you want to install 10.2. it may work for you for a little while, but then you could possibly lose all your information. so i wouldn't advise attempting installing 10.2 without the correct firmware.
