5g with Mac and Windows?

Can I use my 5g ipod with both a Mac and Windows PC? I've been syncing with my Mac but I also have a PC. I downloaded the Ipod updater for Windows XP and installed it. When I connect my Ipod I receive a message that the Ipod cannnot be read and needs to be formatted. Will this formatting erase all data and not allow syncing with the Mac? Thank You,
Charles

Hi Charles, welcome to Discussions. You will need to reformat the iPod with Windows, then it work with the Mac. A Mac formatted iPod will not work with Windows. When it is formatted via the PC, you can resynch with the Mac, to upload your data. After this, set synch to manual, so you can use both computers.

  • External Hard Drive Compatible with Mac and Windows?

    So my old laptop is a Dell Latitude and I bought a Western Digital external hard drive and put all my files/pics/music on it. The information the WD came with said its compatible with Mac and Windows, but when I plug it into my brand spankin new Macbook, it doesn't register with the computer and won't show up. What's going on?
    Message was edited by: philliesphan

    I recently ran into that problem. In order to have the hard drive compatible for both PC and Mac it must be in a FAT32 format. In order to do this though all your files will be deleted (in order to reformat). You can do this by plugging in the hard drive into you mac and going under disk utility and there you will find your hard drive and under erase change the format to FAT32 and then you press erase (all will be deleted off the external drive though)

  • How can I make an icon that links to a webpage that works with Mac and Windows??

    Hi!
    I burn CDs with my photos and send them to clients.   Besides the photos folder, I would like to include a file (similar to the .webloc files on the Mac Desktop) that can be clicked and it will be linked to my website - it will open up a browser window and go to my website .      Is it posssible to make one of these icons that works with both Macs and Windows machines?  Thanks!

    Now it works!  Thanks, Denico!
    The reason I saved to text:   The first time I followed your instructions, it did not work.   I tried to figure out what I did wrong and saw that you wrote to "save as plain text."   I did not know what this means and there was no option available to save a plain text.  So I looked around and saw "save as stationery" and I guessed that maybe that was what you meant.   And after that, it worked!  But the next thing you know, the icons started duplicating themselves.
    I guess I had made a different mistake in the beginning and I fixed it without knowing what it is.
    Thanks for clearing that up.
    But just one question.  WHY does saving as "stationery" make an icon duplicate itself?

  • Best external hard drive format for use with mac and windows?

    This is more of an apple operating system combined with windows operating system question, but being that my OS will upgrade an fluctuate there is not option to choose in the operating system section.
    Anyways to the question(s)
    This whole prbolem came about when my computer started having issues, I want to back it up and whether I can continue to use my laptop or not I will still be owning an apple in the future. I went to buy a hard for back up and got told that it is not as easy as one would think to transfer files from mac OS to windows OS and vice versa. I have a mac, my boyfriend has a windows computer; we share files. Mostly I just copy his files, but once in a while I give him files too. I have read up and talked to people and only found one solution so far to format the external drive to fat 32 or exfat. I think only mac has the exfat option, but works well between both OSs, correct me if I am wrong.
    What is the difference between fat 32 and exfat?
    A user posted some good info about formatting. More specifically .Drives, partitions, formatting w/Mac's + PC's
    https://discussions.apple.com/docs/DOC-3044
    If I do not want to use fat32 or exfat is there a format type that works great for mac saving that I can still at least save files to that were originally on a windows computer? Such as I copy his files from his external drive to my computer and then save them to my external drive.
    Is there a better format for file sharing between mac and windows that does not set a 4GB limit?
    And a silly question, Can you dual format a hard drive?
    Note: This format is for an external hard drive.

    I still do not know which format would be the best. That is so that I can use it easily between mac OSX and windows. Is FAT32 the only true option? How limited is it? I heard it is limited to 4GB file size for windows and 32 GB for Mac. Are there other sources I have not found with more concrete information on the limitations of this format?
    I really do still need this information and I need to back up my drive before I can take the computer in for service.

  • Airport express with mac and windows

    No problems at all with mac and airport express but I have a vaio with window xp sp2 and a pc with vista home premium and even if they connect to the wireless network they cannot receive an ip address. How can I solve this problem? ( As always, we have to waste a lot of time when we work with microsoft operating systems... ;-)) )
    Thanks

    Thank you for providing me with the exact model of your PowerBook. This model was available with either an optional or built-in AirPort Card. This card is only able to connect to 802.11b wireless networks with a maximum bandwidth of 11 Mbps. This card is also capable of connecting to wireless networks that use the TKIP encryption protocol. This protocol is used in either the WEP or WPA standard. The card is NOT capable of connecting to wireless networks that use the AES/CCMP encryption protocol that is part of the WPA2 standard.
    However, some of the earliest versions of the AirPort Card did not work with WPA's TKIP implementation ... so it is possible that you may not be able to connect to an AirPort Express Base Station (AX) configured for "WPA/WPA2 Personal." It may also be problematic to connect to the same AX if it is configured to use one of the 802.11n modes that offer compatibility to 802.11b/g clients. This latter item does not sound like an issue as you are connecting, but wireless security does.
    WEP introduces its own set of "problems." Not to mention, that is it completely un-secure. The following Apple Support article may be helpful in getting all of your wireless clients connected when using WEP: Joining an encrypted WEP or WPA Wi-Fi network 

  • Copy CD with Mac and Windows Files

    I have a CD, not copy protected that has both Mac files and Windows files on it. Specifically it is a Printer Driver CD.
    When I make an image of it with Disk Utility, the only files in it are the Mac files. I wanted to make a safe backup of the CD, including both the Mac files (for my PB G4) and the Windows files for when I install the print drivers on my new MacBook Pro using BootCamp.
    Any ideas as to how to make a copy of a CD that has both Mac and Windows files on it?
    Thank you

    Are you sure the Windows files aren't there? A lot of CDs are hybrids, and do not show the files that belong on another platform such as Windows. Put it in a Windows computer and check.
    Otherwise, buy a copy of Toast and dupe it that way.

  • What format for my external drive allows use with Mac and Windows?

    I got an external hard disk (1 tr) and i want to used it for my windows and mac, i read i can have two partitions one for mac and one for windows, but i dont really want to have two parts, and I read i can format it by fat32 and i can write and read on both os, is that true?
    I want to use it for movies, os backups, and files..
    Is it true that i can only save files up to 4 GB when the format is fat32?
    please advise..

    It this case you would need to to go to "Disk Utility" on mac and select 3 partions which will be under the Parition Layout in my screen shot below. "Current" is grayed out that will drop down select 3 partitions and make one NTFS, second Mac OS Extended, third FAT32. Using the FAT32 for both Mac and Windows but the files have to be under 4GB each.

  • External HDD to be shared with Mac and Windows XP

    I wish to share an external HDD via firewire/USB between an ibook G4 on OSX 10.3.9 and Windows XP. Apart from using FAT32 and having partitions for each OS just in case can anyone share any risks considerations I need to be aware of? I intend on having a generic 320Gb Seagate drive installed into an aluminium box but for some reason Lacie seem to be particularly good with Mac's and I can't ascertain why.
    ibook G4   Mac OS X (10.3.9)   Acer Windows XP

    There appears to be some misunderstanding about what systems can read or write what hard drives.
    OS X can read and write HPS+ and FAT32 formatted drives, and can read, but not write to NTFS drives. Windows can read and write NTFS and FAT32 drives, and cannot read nor write HPS+ drives. Fresh out of the box the only read/write file sharing is via FAT32 drives.
    There are reasonable methods for expanding this capability.
    (1) Windows can be given the ability to read and write HPS+ drives by installing MacDrive 6 on the Windows machine. As far as I know there is no software available which gives OS X the ability to read and write NTFS drives - - maybe it exists or is under develpment somewhere.
    (2) Both OSX and Windows can read/write files that are on a networked file server regardless of the file system used by that file server. The server hides its underlying file system from clients. Just connecting a network capable HDD to a router is NOT the same thing as having a file server on the network - - the same basic file limitations still exist.

  • Sync with Mac and Windows issue

    I bought my wife an iPod (our first). I use a MacBook Pro and she uses a Windows desktop. I copied all of my iTunes music onto the new iPod for her from my Mac. I downloaded iTunes to her Windows machine and tried to sync with it, but it says the iPod must be reformatted for Windows and that will wipe out all of her music files. Is there a way that I can copy the music files to the Windows machine so that she doesn't have to use my computer to sync? These are not protected files. All were copied from our CDs.

    OK first thing to know is that Windows machines can not (without $$$ software) read Mac formatted iPod. However Macs can read and use Windows formatted iPods just fine. So go ahead and format the iPod on the windows machine.
    Next, you will want to transfer your library from the Mac to the Windows machine. If your library is smaller than the total capacity of the iPod, then you can plug the iPod into her Windows machine and then configure it (a checkbox) to enable disk mode. Eject the iPod and plug into the Mac. The iPod should show up in the Mac's iTunes, but also on the desk top as a disk drive.
    At this point it is a simple matter to copy the iTunes folder from the Mac onto the iPod. Eject the iPod, then plug it back into the Windows machine, and copy the stuff off the iPod (as a disk drive) to the Windows hard drive.

  • Can I Use a network drive to work with Mac and Windows?

    Is it possible to introduce a network drive which can be accessed by both Mac and PC? I manipulate images in Photoshop on my Mac but the software I use to create slide shows is only available in PC format. This software is used more or less universally in the area of photography I am invo;ved with so changing is not an option. Can anyone advise me please.
    TC

    Yes sure. Any NAS type drive formatted in any way will work. Both Mac OS X and Windows communicate by Ethernet Packets to a Networked drive and it is up to the NAS device OS to translate those Ethernet Packets to the format used on the drive.
    Even if you are using a standard external drive connected to a Router or another computer, which is what a NAS is (A self contained computer with Operating System and hard drives), that router or NAS box does all the translating.

  • Sync Palm treo with Mac and Windows

    Have a Palm Treo 650 for both personal and work use. Unse a Windows box at work and a Mac at home. I can sync the Palm with my Mac, and I can sync it with Outlook in Windows, but doing this leads to problems, especially multiple entries in both calendar and contacts.
    What I'd like to do is set the Palm up to sync with Outlook on the Windows box, and have it overwrite the data on the Mac when I sync at home. I can't find options for this in iSync 2 (merge data or overwrite device).
    Any suggestions?

  • Sync library with mac and Windows, iTunes 12

    Hi everyone,
    I recently got my iPhone 6, running iOS 8.1.2. I have a mac and a Windows computer and I want to sync libraries on both without having to erase them. The fixes I found on the internet are either for those who have two of the same platform, either mac or Windows, or are for the older versions of iTunes. Third party sync apps didn't work. I don't know where in the new iTunes files the library ID is saved so I can make duplicates. I'm pretty hopeless. Any suggestions?

    Supposedly there is a hidden library ID that is used when syncing but if you change the ID on a second library to match the first one it won't make it the same library.  If you really want the same library on both computers there are a number of ways to do it, but not the brainless Star-Trek computer type solution where you just wish it and it just appears.
    The only true way to achieve this is to use exactly the same library with both computers. This might be achieved through using a common external hard drive or network drive.  Oh, I guess you could keep on copying it back and forth between the two computers too.
    I have never needed to do any of this so I can only make suggestions.  You could create a library and then copy it to the other computer.  It may establish with the same ID.  The only thing is if you then start modifying the library and the two drift apart in content, playlists, ratings, etc.  They may still both sync but obviously things won't match any longer and if you add one new song to your library one one computer it may end up doing major syncing with the phone.

  • I recently purchase macbook air with OS 10.10.2. I want to use my Seagate external backup plus hard drive for time machine back up. How to partition my 1TB Seagate back up plus hard drive for use with mac and windows pc?

    Hi All,
    I recently purchased 13" Macbook Air with OS 10.10.2. I want to use my 1TB Seagate backup plus external hard drive as time machine and my windows 7 pc. Please suggest a method. Thanks in advance for your reply.

    I strongly recommend having an external drive dedicated solely for TimeMachine. You could partition the drive but if something goes wrong you risk losing the data on both partitions. Should you decide to go ahead with splitting the drive for two different uses you’ll need to partition the drive either using the Mac’s built in Disk Utility program or Windows utility. I believe the built in Windows disk utility program will destroy the current partition and erase the data that’s on it - I use a third party Windows disk utility program for partitioning and it allows for non-destructive partitioning but warns to back up data first just in case. Apple’s Disk Utility can do non-destructive partitions but I don’t recall every trying to do a non-destructive partition on a disk originally formatted for Windows using it. Again - back up that data just in case.
    Finally, your TimeMachine drive should be at least 1.5 times (I prefer 2 times) the size of the data you expect to be backing up a year or two from now.  In other words, if you currently are using 50GB of your computer’s drive but expect to begin purchasing Mac software to replace software on your Windows computer and if you expect to be putting photos, music, and other data on it you might expect that two years from now you’ll have 100GB of stuff on the drive. So a 200GB partition is the smallest size you’d want.  TM’s backup scheme keeps multiple copies of data as it changes so the extra room is important for this scheme.

  • What antivirus is better for those who work with mac and windows?

    In my home I use an iMac, but in college I use Windows, and more than once I found an infected file. I know not affect iMac, but I prefer that viruses are removed. Right now I use ClamXv, but I don't know if it is effective.
    Am I to continue using ClamXv? or, do I use another?
    If there are others better AV for mac, what is most recommended?
    **I have also used Sophos, but it makes the iMac go very slow.
    Thanks for your attention.

    1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to your computer, or who has been able to log in to it remotely. 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.
    If you find this comment too long or too technical, read only sections 5, 6, and 10.
    OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
    It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
       3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    It can easily be disabled or overridden by the user.
    A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
    An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
    For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandboxing security is based on user input. Never click through any request for authorization without thinking.
    4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
    5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating 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. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
    Any website that prompts you to install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
    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 visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
    Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
    Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders," for example, are outside the safe harbor, though not all are malware.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
    There is an increasing tendency for rogue websites such as "Softonic" and "CNET Download" to distribute free applications that have been packaged in a superfluous installer that also installs malware or something else that you don't want. Never visit those sites, and get all freeware directly from the developer's own site whenever possible.
    Software attached to email that you didn't request is unsafe, even if it comes (or seems to come) from someone you trust.
    Software advertised by means of spam is unsafe.
    Unknown "free" software that a stranger on the Internet is eager for you to download is unsafe.
    Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
    "FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
    I don't say that leaving the safe harbor just once will inevitably result in disaster, but making a habit of it will weaken your defenses against malware attack. Doing any of the things alluded to above should make you uncomfortable.
       6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
    Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
    7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store — nothing else.
    Why shouldn't you use commercial "anti-virus" products?
    To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. New threats are emerging on a daily basis. Research has shown that most successful attacks are "zero-day" — that is, previously unknown. Recognition-based malware scanners do not defend against such attacks.
    Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
    In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
    8. An anti-malware product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware, and even for that use it's not completely effective. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
    A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
    ♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
    Anti-virus software may be able to tell you which particular trojan it is, but do you really care? In practice, there's seldom a reason to use the software unless an institutional policy requires it. Windows malware is so widespread that you should assume it's in every unknown email attachment until proven otherwise.
    The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
    10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. "Hmmmm, this torrent is a crack of that new game I want. I think I'll download it. It could be a trojan, but the antivirus will warn me if it is." Then they wonder why their Mac is so slow all of a sudden.

Maybe a week later the antivirus does warn them, but what good does that do?
