Apple announced its latest mobile operating system update, iOS 12, during its Worldwide Developer Conference on Monday, revealing upgrades to security, privacy and digital health services that seemed to target some of its biggest competitors. 

"Today it was more clear than ever that they really wanted to draw a hard line between where they stand vs. where Google and Facebook stand," said Loup Ventures analyst Gene Munster. 

Apple also unveiled its new macOS Mojave, for instance, and revealed greater protections on apps and tools that use personal data. The company also unveiled an enhancement to Safari that prevents data companies from tracking users through social media plugins and comment fields, which happens to be a way that sites such as Facebook use to collect data on users when they're not on their platforms.

The new features Apple announced also build and improve upon iOS 11.4's existing capabilities such as augmented reality and Siri's voice commands, and center around improving the user experience.

3. -- Elon Musk Faces Investor Challenges at Tesla Meeting

Amid pressure from CtW Investment Group, Tesla Inc. (TSLA) shareholders will vote Tuesday on whether to boot Elon Musk as chairman and wave goodbye to three directors.

Working against Musk is a struggling stock price, ongoing Model 3 production woes and a month's long tweet-storm that has called into question Musk's ability to lead.

Former hedge fund manager Whitney Tilson got caught on the wrong side of the trade in shorting Tesla a few years ago and he warned in an interview with TheStreet that the time for Tesla's stock to take a tumble is fast-approaching.

Tilson said Tesla will need to raise a lot of capital, and access to that capital may be in short supply.

"My gut instinct is that after the last conference call, Musk's increasingly erratic behavior has shaken the confidence of analysts at big firms like Fidelity that sort of make the recommendation to put more capital into Tesla," Tilson said. "It's now a career risk for people like that to be recommending Tesla, which means they could have trouble accessing capital. And they are going to need to access a lot of capital at the rate they are burning it."
