For now, the only security-related update Apple is still releasing for Snow Leopard is its XProtect "[un]Safe Downloads List," but there's no way of knowing for sure how much longer Apple will continue to update it. Meanwhile, the now three-generations-old Lion operating system is currently still getting both XProtect and iTunes updates. However, these will likely be just about the only things Apple continues to update for Lion over the next year. Development of OS patches costs Apple money and developer resources. Although the same could be said for iTunes updates, Apple has a financial incentive to keep iTunes updated: the iTunes Store and the iOS App Store, both of which are accessible via the iTunes Mac app, bring in a lot of revenue for Apple.

Unfortunately, nobody knows for certain how long Apple will continue to release security patches or XProtect updates for any given operating system. Although Microsoft publicly announces its support timetables for Windows, and the Ubuntu Linux company Canonical does likewise, Apple has never given any official word to the public regarding how long each version of Mac OS X or iOS will continue to receive security updates, and Apple consistently ignores press inquiries about when levels of support will be dropped for its operating systems.

The good news is that most new Macs sold within the past several years can be upgraded to Yosemite. Following is the list of Macs that can run a supported version of OS X. If your Mac is older than the ones listed, read on for suggestions on what you can do to upgrade to a supported system. You can do a direct upgrade from Snow Leopard v If you still have an earlier version of OS X on your compatible Mac, you will need to download Yosemite on another compatible Mac with If your Mac isn't new enough to run Yosemite, then unfortunately it's not capable of running an Apple operating system that's still fully supported.

However, if your Mac has a Core 2 Duo processor one of the models listed below , and as long as it has at least 2 GB of RAM and 7 GB of free hard drive space, it should still be able to run Lion which, although increasingly less safe to use now, is at least better than Snow Leopard or earlier because it had been getting security updates until recently :. If Lion is the newest version of OS X that will run on your Mac, but you never purchased it while it was available in the Mac App Store, you won't be able to find it for sale there anymore.

Those who are unsure which Mac model they own may find EveryMac and apple-history to be useful sites. RAM is cheap, and you can either install it yourself by following guides available online, or simply have an Apple-authorized repair technician do it for you. Remember, even Lion isn't supported anymore, and Snow Leopard hasn't gotten new security updates for quite a while, so it's best to avoid using both of these older operating systems. If you still use a Mac with a PowerPC processor, including G4 or G5 Macs, Apple hasn't released any security updates for your Mac's maximum operating system for over three years now.

Apple hasn't sold any PowerPC-based Macs since Unfortunately, Apple doesn't give users any kind of warning when their operating system or Mac is no longer supported.

Worse, when users run Apple's Software Update program, it misleadingly tells them "Your software is up to date. This means that Mac users often have no idea that they're using unpatched, insecure software that could expose them to drive-by malware installations and other security problems.

Lest you think that nobody would bother releasing malware to attack such old systems, in recent years malware has been found in the wild that was designed to attack multiple platforms, and occasionally this malware has contained PowerPC native code. This didn't just happen once; it has happened again and again. Universal binary malware can run on old Macs, too.

Uninstalling AVG AntiVirus for Mac | AVG Support

Image credit: Kaspersky. While Apple boasts about the extremely high percentage of iPhone, iPad, and iPod touch devices that are rapidly upgraded to each major new version of iOS, such is not necessarily the case with Macs and OS X. That's not terrible given that it's been out for less than a month.

Scanning Documents & Photos on a Mac

This makes non-upgraded Macs a potentially significant target for criminals interested in infecting large numbers of computers. Anyone still using Lion, Snow Leopard, or an earlier version of Mac OS X should strongly consider upgrading to Yosemite if their Mac supports it, or if not, they should buy new hardware if they can afford it. Let's face it, that's what Apple wants you to do anyway. But what can you do if Yosemite is not supported on your Mac and you can't afford to buy a new computer? If you have an older Intel Mac, you have several options. While Apple may not support your Mac anymore, ironically Microsoft does; Windows 8.

Oddly enough, even Windows 10 Technical Preview's system requirements hint that Windows 10 will probably run on your old Intel Mac. Microsoft's skipping the name "Windows 9," by the way. Alternatively, if you can't afford to buy a copy of Windows, or aren't interested in risking all your data to a pre-beta operating system, or just can't stand the thought of running Windows on your Mac—or if you prefer to support free and open-source software—there are guides online detailing how to install Ubuntu Linux on a Mac.

The latest versions of Ubuntu are even still being made available for PowerPC-based Macs , including those with a G3 processor. At the time of this writing, Another option is, of course, to buy a cheap PC, tablet, or Chromebook, assuming it will do all the things for which you personally need a computer.

Be forewarned: you get what you pay for, and moving from the cohesive Apple ecosystem to something else may be difficult. The average Mac user probably won't be excited about any of those options.

À vous la parole

I suspect that most Mac users, geeks and non-geeks alike, would rather buy a newer Mac than switch to another platform altogether. If you can't afford to buy a brand new Mac but you do have a little bit of money to spend, you can shop around for used Macs, but make sure you buy one that's new enough to support Yosemite so it will hopefully be able to get security updates for a couple more years. If you know a Mac user who's still running an older version of OS X , do them a favor and check to see whether their Mac is capable of running Yosemite.

If so, help them upgrade. If not, let them know it's time to strongly consider getting a newer computer. The burden of informing users about software and hardware that will no longer receive security updates should really fall on Apple—not on security researchers, security blogs, or blog readers. Let's hope Apple eventually figures this out and starts giving users clearer notifications when they need to upgrade lest they put their digital safety at risk. It's highly unlikely that Mac OS X v Thanks for the great, informative article Joshua.

Quad-core 3. And just like other articles say as well. I would greatly appreciate any feedback. Your system is no longer supported. It is a Xeon based on the Core 2 Quad lineup. Your processor supports 64 Bit Operating systems but the firmware under it is 32bit. Google a guide and start reading. Ping is a pretty simple utility. This is repeated a certain number of times—five by default under windows and until it is manually stopped by default under most other implementations—and it then compiles response statistics. It calculates the average delay between the requests and their respective replies and displays it in its results.

For ping to work, the pinged host must abide by RFC which specifies that any host must process ICMP echo requests and issue echo replies in return. Most hosts do reply but some disable that functionality for security reasons. Firewalls often block ICMP traffic too. Pinging a host which does not respond to ICMP echo requests will provide no feedback, exactly like pinging a non-existent IP address.

To circumvent this, many IP address scanning tools use a different type of packet to check if an IP address is responding. Our selection of IP address scanning tools for the Mac includes both commercial software and free and open-source tools. Most of the tools are GUI-based although some are command-line utilities.

Some are rather complex and complete tools while others are just simple extensions of the ping command to include some way of scanning a range of IP addresses without having to issue multiple commands or to write a scanning script. All these tools have one thing in common: they can all return a list of all the IP addresses that are responding within the scanned range.

Despite being deceptively simple Angry IP Scanner does exactly what one would expect and it makes extensive use of multithreading. This makes it one of the fastest tools of its kind. This tool will not only ping IP addresses, but it will also optionally run a port scan on discovered hosts. As for the scan results, they are by default displayed on the screen in table format but they can easily be exported to several file formats such as CSV or XML. LanScan from Iwaxx is available from the Apple app store. It is a free, simple and efficient IPv4-only network scanner.

It can discover all active devices on any subnet. It could be the local one or any other subnet that you specify.

In fact, it is quite flexible when it comes to specifying what to scan and it can be as small as a single IP address and as large as a whole network. This product has several advanced features. It will, for instance, auto detect configured interfaces. In-app purchase will let you upgrade the app to the pro version which has only one extra feature: it will display the full hostname of each discovered host.

The free version will only display four full hostnames and the first 3 characters of the remaining ones. The product is free for use on small home networks of up to six devices and paid Home and Pro versions are available for larger networks. The tool yields powerful results yet it is easy and intuitive to use. Local networks are scanned automatically and custom IP address ranges can be added and scanned manually. IP Scanner for Macintosh is designed to allow you to customize your scan results.

Once a device has been identified, you may assign it a custom icon and name to more easily recognize it at a glance. It can also give you an overview of the current network or show you changes over time.

The results display is highly customizable and you can adjust columns, text size, bezel transparency, and more. At some point in time you may have installed the popular Malwarebytes tool on a Mac to scan for malware, spyware, ransomware , junkware, and other garbage threats on a Mac, but at some point you may decide you want to uninstall Malwarebytes from the Mac and remove the utility from a computer. Apple has released a series of interesting ASMR videos to listen to and enjoy with headphones on.

The videos emphasize different sounds, like falling rain, the sounds of boots on a trail, the sounds of workworking, and the sound of someone whispering. Apple recommends wearing headphones for the best experience. ASMR, which stands for Autonomous Sensory Meridian Response, is apparently supposed to trigger positive feelings or tingling in the listener in a similar way to using a scalp massager.

The Apple ASMR videos have been embedded below for trying out yourself, Apple says they are best enjoyed wearing a set of headphones. The new public beta builds match the iOS 13 beta 6 developer build from the day prior. The new beta builds are currently available to users who are enrolled in the developer beta testing program for iOS and iPadOS.

Typically a developer beta version of iOS 13 and iPadOS 13 is released first, and is soon followed by a public beta build that is labeled as a version number behind. For example iOS 13 dev beta 6 is typically iOS 13 public beta 5, even if they carry the same build number. Need to convert a Numbers file to an Excel spreadsheet file from iPad or iPhone?
