From Apple.com:
Electrodes built into the Digital Crown and the back crystal work together with the ECG app to read your heart’s electrical signals. Simply touch the Digital Crown to generate an ECG waveform in just 30 seconds. This data can indicate whether your heart rhythm shows signs of atrial fibrillation — a serious form of irregular heart rhythm — or sinus rhythm, which means your heart is beating in a normal pattern.

Each beat of the heart sends out an electrical impulse. With the ECG app, Apple Watch Series 4 can read and record these impulses by connecting the circuit between your heart and both arms.

The resulting ECG waveform, its classification, and any notes you’ve entered on related symptoms are automatically stored in the Health app on your iPhone. You can share them with your doctor and have a better-informed conversation about your health.

In cases that require more extreme forms of this power management, the user may notice effects such as:

– Longer app launch times
– Lower frame rates while scrolling
– Backlight dimming (which can be overridden in Control Center)
– Lower speaker volume by up to -3dB
– Gradual frame rate reductions in some apps
– During the most extreme cases, the camera flash will be disabled as visible in the camera UI
– Apps refreshing in background may require reloading upon launch

To get your battery replaced, visit the Contact Apple Support page, click on See Your Products, sign in to your Apple ID account, select which iPhone, and click on Battery, Power, and Charging and then Battery Replacement.

After completing the above steps, you should have options available to you to take your iPhone to an Apple Store or Apple Authorized Service Provider, mail the device to an Apple Repair Center, or both.

1. Go to: ~/Library/Containers/com.apple.Preview/Data/Library/Preferences/
2. Locate and open the preferences file – com.apple.Preview.plist
3. Set “PVPDFSuppressSidebarOnOpening” to false
4. If you don’t see it, simply add the following to com.apple.Preview.plist:
   <key>PVPDFSuppressSidebarOnOpening</key>
<false/>

UPDATE FOR HIGH SIERRA:
Twitter user @ZiadFazel wrote in with an update for Preview in Mac OS X High Sierra.

From TechCrunch:
The study involved 6,158 participants recruited through the Cardiogram app on Apple Watch. Most of the participants in the UCSF Health eHeart study had normal EKG readings. However, 200 of them had been diagnosed with paroxysmal atrial fibrillation (an abnormal heartbeat). Engineers then trained a deep neural network to identify these abnormal heart rhythms from Apple Watch heart rate data.

Each year, more than 100,000 strokes are caused by an abnormal heart rhythm called atrial fibrillation – the most common abnormal heart rhythm responsible for 1 in 4 strokes. It’s pretty amazing to think that soon there will be technology available on our wrists that can identify and warn us of abnormal heart rhythms, including atrial fibrillation.

*I’m proud to have participated in the Heart eHealth study and am currently participating in the mRhythm study, the goal of which is to compare the heart rhythms gathered by the FDA-approved AliveCor monitor against those from the Cardiogram App/Apple Watch to assess its validity and accuracy in detecting arrhythmias.

I took the usual troubleshooting steps of toggling wi-fi off and on,  restarting the machine, creating a new location in Network Preferences –   even manually configuring DNS to use Google’s public servers. Nothing worked. Then I ran across this article at OSXDaily.com that suggested specifying a lower custom MTU setting of 1453. That seems to have done the trick.

Here are the steps I took that fixed my wi-fi issues (see the full article for additional troubleshooting steps):

1. Pull down the Apple menu and choose “System Preferences”, then select “Network”.
2. Choose Wi-Fi from the left list in the Network panel.
3. Pull down the “Location” menu and select “Edit Locations”.
4. Click on the [+] plus button to create a new network location with an obvious name like “Custom WiFi Fix”.
5. Use the Network Name dropdown menu and select the wi-fi network you want to connect to.
6. Now choose the “Advanced” button in the corner of the Network panel.
7. Go to the “TCP/ IP” tab and choose “Renew DHCP Lease”.
8. Now go the “DNS” tab, and under the “DNS Servers” list section click on the [+] plus button, adding each IP onto its own entry: 8.8.8.8 and 8.8.4.4 – these are Google Public DNS servers that are free to use by anyone but you can pick different custom DNS if you’d prefer to set custom DNS.
9. Now select the “Hardware” tab and set the “Configure” option to “Manually”, then adjust the “MTU” option to “Custom” and number to “1453”.
10. Now click on “OK” and then click on “Apply” to set the network changes.
11. Exit out of System Preferences and open an app that uses the internet like Safari, your wi-fi should work great now.

Thanks to the guys over at OSXDaily for putting this together. It’s been a great help.

I can still remember some of those early meetings, with 3 or 4 of us in a locked room somewhere on Apple campus, with a lot of whiteboards, talking about what iMovie should be (and should not be). It was as pure as pure gets, in terms of building software. Steve would draw a quick vision on the whiteboard, we’d go work on it for a while, bring it back, find out the ways in which it sucked, and we’d iterate, again and again and again. That’s how it always went. Iteration. It’s the key to design, really. Just keep improving it until you have to ship it.

I think in many ways Apple still adheres to this philosophy of releasing an MVP and continuously iterating again and again and again until they have a polished, mature product.
