These are the most popular computer operating systems from 1985 to 2024, based on market share. The latest numbers from 2003 on are readily available from Wikipedia and Statcounter. The first half of the video required a bit more research, which entailed finding and converting sales figures into market share. These numbers may be different based on what OSes are included in the stats, this is why different videos have slightly different numbers.

Apple has released previews of its upcoming mobile and desktop operating systems, introducing several new features as well as opening up some built-in applications to third-party app coders. Apple's desktop operating system is dropping the OS X moniker in favour of macOS, Apple said at its Worldwide Developer Conference (WWDC) in San Francisco today. The Siri digital assistant will make it into the next version of macOS, which has been dubbed 'Sierra'. Siri on Sierra can be used to find files and documents, calendaring and messages. Search results from Siri in the macOS notifications centre can also be copied and...

Adding to the evidence that Apple is intending to change the name of OS X, the company on Thursday posted an updated webpage referring to the software as "MacOS" instead. The term can be found on an FAQ page within Apple's Environment subsite, specifically in a section about greenhouse gases and product lifecycles. The text is the only direct reference to either Macs or OS X in the FAQ — notably, the rest of Apple's website still appears to insist on using "OS X." In late March it was discovered that one framework in OS X 10.11.4 refers to "macOS."...

Adobe-FlashAdobe has issued Flash Player security updates for OS X, Windows, Linux, and Chrome OS to address "critical vulnerabilities that could potentially allow an attacker to take control of the affected system" by way of ransomware. Ransomware is a type of malware that encrypts a user's hard drive and demands payment in order to decrypt it. These type of threats often display images or use voice-over techniques containing instructions on how to pay the ransom. In this particular "CERBER" attack (via Reuters), affecting Flash-based advertisements, attackers have reportedly demanded between around $500 and $1,000, to retrieve the encrypted files. Adobe...

“Apple updated its OS X desktop operating system yesterday (Mar. 21) to version 10.11.4, which fixes dozens of system vulnerabilities, solves an annoying bug in Safari and adds a password to Notes,” Henry T. Casey reports for LAPTOP Magazine. “The new version also increases USB reliability and adds support for Apple’s animated Live Photo files.” “The most well-publicized flaw patched in the security updates protects users from targeted attacks that could poach images or videos sent via iMessage,” Casey reports. “OS X users who use Notes as their primary app for writing quick documents will also want to update to...

The first known ransomware targeted at Apple's Mac computers was only downloaded about 6500 times, according to a representative for the Transmission project, whose software was used to launch the attack. Transmission representative John Clay said the ransomware was added to disk-image of its software after the project's server was compromised in an attack. "We're not commenting on the avenue of attack, other than to say that it was our main server that was compromised," he said. "The normal disk image [was] replaced by the compromised one." He said security on the server had since been increased and the group...

Apple has shut down what appears to have been the first, fully-functional ransomware targeting Mac computers. This particular form of cyber threat involves malware that encrypts the data on your personal computer so you can no longer access it. Afterwards, the hackers request that you pay them in a hard-to-trace digital currency – in this case, bitcoin – in order for you to retrieve your files. This ransomware, called KeRanger,” was first reported by researchers at Palo Alto Networks. They also noted that Apple has now revoked the abused certificate that was used in the attack and updated its built-in...

A unique scareware campaign targeting Mac OS X machines has been discovered, and it's likely the developer behind the malware has been at it a while since the installer that drops the scareware is signed with a legitimate Apple developer certificate. "Sadly, this particular developer certificate (assigned to a Maksim Noskov) has been used for probably two years in similar attacks," said Johannes Ullrich, dean of research of the SANS Institute's Internet Storm Center, which on Thursday publicly disclosed the campaign. "So far, it apparently hasn't been revoked by Apple." Ullrich said he happened upon the scam while investigating some...

Security is something that is always on the minds of users these days, and that includes those who use Linux. TechWeek Europe has a disturbing article about a Linux trojan that captures audio and takes screenshots. It remains to be seen how widespread this Trojan is among Linux users and what the exact attack vector is for it. Steve McCaskill reports for TechWeek Europe: Security researchers have found a new Linux Trojan capable of taking screenshots of infected systems and even recording sound. Russian anti-virus firm Dr Web says that once the Linux.Ekoms.1 malware is launched it checks for two...

In a study conducted by CVE Details, the most vulnerable software of the previous year has been identified as Apple’s OS X and the tech-giant is also the company with most bugs. With 2016 coming, people in all sectors have been busy summarizing 2015 with reports and lists of who have been the winners and who have been the losers. The tech experts and security personnel have been at it too, with CVE Details producing a list of most vulnerable software of the past year. Many would have expected the list to be topped by Adobe Flash, for the software...

Today marks a huge milestone for Steam on Linux: 1,500 games are natively available! This is quite significant while Windows is at 6,464 and OS X is at 2,323.New games continue to be ported to Linux and offered via Steam almost daily. This is all while the Steam Linux market-share is below 1%. Heck, even stats well outside the gaming space show Linux desktop use at less than 2%.While the Linux gaming marketshare right now is very tiny, game developers continue porting to Linux in anticipation of a return on investment down the road as more gamers try out SteamOS...

Just days after patching the DYLD_PRINT_TO_FILE vulnerability with a new OS X point release, Apple's desktop operating system has been hit with yet another zero-day exploit that would allow an attacker to gain root access without using a password. Luca Todesco on Twitter The exploit was discovered by Italian developer Luca Todesco, who relies on a combination of attacks — including a null pointer dereference in OS X's IOKit — to drop a proof-of-concept payload into a root shell. It affects every version of OS X Yosemite, but seems to have been mitigated in OS X El Capitan, which is nearing release....

Apple is reportedly working on a fix to eradicate a dangerous bug that could allow unauthorised users access to Mac OS X Yosemite machines. The Guardian’s sources say Apple will release a security update to wipe out the so-called "zero day" DYLD bug as soon as possible. The “privilege escalation” bug potentially allows third parties to gain administrator access to a Mac without a password. The fix for Mac OS X 10.10.5 Yosemite will arrive shortly, ending worries that the vulnerability wouldn't be plugged before the next version, El Capitan, comes this autumn. In the meantime, the paper says Apple...

It’s Black Hat season, meaning that we are getting a new batch of zero-day exploits showing how insecure our gadgets are. Xeno Kovah and Trammell Hudson found a serious zero-day vulnerability in OS X letting malware creators completely brick your Mac without any way to reset it to its factory status. Apple told The Guardian that it is working on a fix for both Yosemite and El Capitan. This zero-day exploit dubbed Thunderstrike 2 targets your Mac’s firmware thanks to an attached Thunderbolt accessory, such as an Ethernet adaptor or an external hard drive. After receiving the code via a...

Apple has quietly included a large amount of security fixes in its latest set of patches for its OS X and iOS operating systems, plugging some serious, high-profile vulnerabilities in its code. A tally of the common vulnerability and exposures (CVE) tags in the OS X Yosemite 10.10.4, Security Update 2015-005 and Safari 8.0.7 update packages showed 80 vulnerabilities have been patched by Apple. These range from a flaw that allowed attackers to write to the low-level extensible firmware interface (EFI) - which manages the hardware in Mac computers - when the systems resume from sleep. The EFI zero-day was...

A recently published exploit for the Safari browser demonstrates a URL spoofing mechanism which might convince users they are visiting a legitimate website, when they are actually visiting another site which may be phishing their details. Deusen researchers have disclosed a vulnerability which may be exploited by hackers to hijack user accounts on a range of websites, from social media to banking. The proof-of-concept invites users to visit what appears to be the Daily Mail website – however, a script will execute the loading of another URL before the page users are directed to can be displayed. Tested using Safari...

Love the new MacBook's svelte design, but not a fan of OS X 10.10 Yosemite? There's good news: According to a new test, Windows 10 apparently runs more smoothly on the new MacBook. Alex King, a computer science student studying at Tufts University, spent a month with the new 12-inch MacBook and provided some insightful new details about running the beta version of Windows 10 on it. See also: 5 things Apple didn't say about the new MacBook King installed Windows 10 using Boot Camp, meaning his new MacBook boots natively into Windows 10, as opposed to being emulated in...

Last November, Microsoft said that it would bring some of the core features of its .NET platform — which has traditionally been Windows-only — to Linux and Mac. Today, at its Build developer conference, the company announced its first full preview of the .NET Core runtime for Linux and Mac OS X.In addition, Microsoft is making the release candidate of the full .NET framework for Windows available to developers today [April 29, 2015]. The highlight here, though, is obviously the release of .NET Core for platforms other than Windows. As Microsoft VP of its developer division S. “Soma” Somasegar told...

OS X Yosemite still open to Rootpipe hijacking, says ex-NSA bod Apple's attempt to fix a serious security weakness in OS X has fallen short, leaving users still vulnerable to malware seizing their Macs, it is claimed. Patrick Wardle, director of research at Synack, reckons Cupertino has not been able to fully kill off the so-called "Rootpipe" backdoor that was supposed to be eradicated in last week's OS X Yosemite 10.10.3 update. Apple has refused to address the vulnerability in older versions of OS X, such as version 10.9.x. The Rootpipe vulnerability, present in OS X since at least 2011,...
